Don't register SIGHUP handler without actually handling SIGHUP
In libosmocore, we normally register a SIGHUP handler for log file
rotation.
However, the osmo-pcu code so far installed its own signal handler,
which did exactly nothing in the SIGHUP case.
Let's fix this by removing SIGHUP handling here, letting libosmocore
take care about this.
