[Mellanox] Improve FW upgrade logging (#13465)

- Why I did it
To improve ASIC FW upgrade logging and have information about the cause of FW update failure in the log.

- How I did it
Added syslog logger support

In case the FW update has failed the update tool will give the cause of the failure in the output in the last line, starting with "Fail".
When running the tool, in case of a failed update, we will parse the output to retrieve the cause and log it.
