osmo-trx: Re-introduce -l cmd line parameter

Parameter -l to set the terminal logging levle was removed in
3da1f8352e337fb032bf7a58c2909d3ba918e237, but afterwards it was decided
to keep the cmd line options for a bit more to easy migration to VTY
cfg.

The command line no longer accepts keywords ("DEBUG", "INFO", etc.) but
log level numbers, due to libosmocore APIs log_parse_level and
log_level_str being marked as deprecated and for internal use only.

Keep in mind the log level is overridden by VTY cfg if any line sets log
levels for log stderr in there.

Explicit cast to unsigned int for loglvel is issued to avoid iostream
printing it as a char.
