Subject: [PATCH] [celestica]: Fix E1031 udev rules not work for sonic os first
 boot after be installed (#7043)

Use udevadm to trigger the udev rules on the first boot

How to verify:

- Connect C0 with E1031;
- Install or upgrade the sonic os to 202012 branch;
- When access to sonic check if /dev/C0-1 to /dev/C0-48 are existed.
