Introduce osmo_strlcpy() function so we can stop using strncpy()

I'm aware of the existing criticism on stlrcpy(), but I think it is
still better than what we have now: stnrcpy(), sometimes with Coverity
warnings and sometimes with a manual setting of the termination byte.

The implementation follows the linux kernel strlcpy() which is claimed
to be BSD compatible.

We could of course link against libbsd on Linux instead, but I think
it's reasonably small and simple to provide our own implementation.
Future versions of libosmocore could use some autoconf magic and
preprocessor macros to use the system-provided strlcpy() if it exists.
