LogControl doesn't interact with --no-debug well

[evverx]

Describe the bug
The LogControl1 API doesn't affect logs emitted by polkit when --no-debug option is removed.

To Reproduce
To reproduce it it should be enough to remove the --no-debug option and set the LogLevel to crit. polkit keeps emitting messages like

Expected behavior
polkit should emit only critical messages (and the TRANSPORT should probably be syslog since the LogTarget property says that it all goes to syslog.

It was also discussed in #506 (comment)

FWIW I agree with #425 (comment) that ideally --no-debug shouldn't be necessary. polkit could emit info messages by default and the LogLevel property could be used to control all the logs (by analogy with what all the systemd services do for example).
