[S6100] Improve S6100 serial-getty monitor, wait and re-check when getty not running to avoid false alert.
#### Why I did it
On S6100, the serial-getty service some time can't auto-restart by systemd. So there is a monit unit to check serial-getty service status and restart it.
However, this monit will report false alert, because in most case when serial-getty not running, systemd can restart it successfully.
To avoid the false alert, improve the monitor to wait and re-check.
Steps to reproduce this issue:
1. User login to device via console, and keep the connection.
2. User login to device via SSH, check the serial-getty@ttyS1.service service, it's running.
3. Run 'monit reload' from SSH connection.
4. Check syslog 1 minutes later, there will be false alert: ' 'serial-getty' process is not running'
#### How I did it
Add check-getty.sh script to recheck again later when getty service not running.
And update monit unit to check serial-getty service status with this script to avoid false alert.
#### How to verify it
Pass all UT.
Manually check fixed code work correctly:
```
admin@***:~$ sudo systemctl stop serial-getty@ttyS1.service
admin@***:~$ sudo /usr/local/bin/check-getty.sh
admin@***:~$ echo $?
1
admin@***:~$ sudo systemctl status serial-getty@ttyS1.service

ipmihelper files are repeated for few DellEMC platforms. Removed the
files in sonic_platform since as part of debian rules,ipmihelper will be
copied to necessary directory.
Also add out of tree pca9548 mux driver to use platform data to mapping i2c bus with front panel port.

- How to verify it
hw-mgmt-dump.tar.gz will be found in sonic_dump__< YYYYMMDD_HHMMSS>.tar.gz.
The S6000 devices, the cold reboot is abrupt and it is likely to cause issues which will cause the device to land into EFI shell. Hence the platform reboot will happen after graceful unmount of all the filesystems as in S6100.
Moved the platform_reboot to platform_reboot_override and hooked it to the systemd shutdown services as in S6100
- Make DellEMC platform modules Python3 compliant.
- Change return type of PSU Platform APIs in DellEMC Z9264, S5232 and Thermal Platform APIs in S5232 to 'float'.
- Remove multiple copies of pcisysfs.py.
- PEP8 style changes for utility scripts.
- Build and install Python3 version of sonic_platform package.
- Fix minor Platform API issues.
This patch upgrade the kernel from version

- Fix for Azure/sonic-buildimage#4095
- Exit status from failed make command(action) didnt reached parent target because the make command is inside the "for" loop.
- Only the exit status of the last command in the last iteration of the for loop is read by parent target.
- This is the reason why dpkg-buildpackage ignored the make error.
- Fixed the issue with help of "set -e".
Implement classes IpmiSensor, IpmiFru to obtain platform sensors information for Platform2.0 APIs in DellEMC Z9264 platform.
Add a new file ipmihelper.py with the implementation for IpmiSensor, IpmiFru classes.
