[PATCH pmg-api 2/4] fix #3657: api: tracking center: explicitly set input base from config

[Stoiko Ivanov <s.ivanov@proxmox.com>]

makes it possible to override the location of logs which are scanned
by pmg-log-tracker.
This should enable admins, to either point the log-tracker to another
location on disk where e.g. a rsyslog daemon combines the logs of
multiple instances, or to only log the mail-facility somewhere and
drop /var/log/syslog logging in favor of journalling.

pmg-log-tracker still uses syslog-files over the journal, as this was
far more performant when we last compared log-file reading to reading
from the journal.
