sighandler_t compatibility issue with OpenBSD

[Björn Ketelaars]

Both OpenBSD and FreeBSD use sig_t instead of sighandler_t. This is kind of an
issue for src/occtl/unix.c. Fortunate for us src/common/system.h (which is
included in unix.c) takes great care of handling sighandler_t/sig_t. Proposed
fix:
