meta-ampere: mtmitchell: Support host consoles logger

This commit supports phosphor-hostlogger in STREAM mode, to forward
the byte stream from obmc-console to rsyslog via the imuxsock module.
The logs can be obtained in /var/log/. The logs are rotated by
logrotate. The size threshold of cpu console is 256KB and the others are
64KB. Each log is polled every 1 minute to check if its file size
exceeds the threshold to rotate it to the new file. Each console can be
saved in up to 2 log files.

Tested (CPU console):

1. Change the mux of CPU console to BMC
    $ ampere_uartmux_ctrl.sh 1 2
2. Connect to CPU SOL console
     $ ssh root@<BMC_IP> -p 2200
3. Execute commands in the CPU SOL console
    => The console output on CPU SOL console will all be logged to
       /var/log/obmc-console-cpu.log
    => The log will be rotated to /var/log/obmc-console-cpu.log.1 if the
        original log file size exceeds 256KB every 1min poll
