Wrap osmo_strlcpy() calls

Browse Source 
Using following semantic patch:
@@ expression A, B, C; @@
- osmo_strlcpy(A, B, sizeof(A));
+ OSMO_STRLCPY_ARRAY(A, B);

Which was applied using following command:
spatch --dir src -I src --sp-file strlcpy.spatch --in-place --recursive-includes

All the calls to osmo_strlcpy() which use destination buffer obtained
via sizeof() were replaced with the corresponding wrapper macro.
