hlr.c: properly terminate the process on SIGTERM
As per the systemd.kill manual, when a service is going to be
stopped by systemd, the process will first be terminated via
SIGTERM. If then, after a delay, processes still remain, the
the termination request is repeated with the SIGKILL.
It was observed that osmo-hlr immediately terminates on SIGTERM,
leaving the SQLite database open. As a result, several temporary
files (such as hlr.db-shm, hlr.db-wal) remain, allowing the
further recovery:
DDB ERROR <0001> db.c:86 (283) recovered 10 frames from WAL file
Let's properly handle SIGTERM in the same way as we handle SIGINT.
