[dockers/supervisord]: Don't use deprecated config options

Supervisord emits warnings due to the use of `stdout_logfile=syslog`
and `stderr_logfile=syslog`.  Replace with the modern configuration
options of `stdout_syslog=true` and `stderr_syslog=true` and set
the log file itself to `NONE` so it doesn't generate a file-based
log.

Warnings corrected look like:
```
2024 Dec  1 15:31:06.467218 sw2 INFO pmon#supervisord 2024-12-01 15:31:04,033 WARN For [program:xcvrd], stderr_logfile=syslog but this is deprecated and will be removed.  Use stderr_syslog=true to enable syslog instead.
```
