Makefile: silence GCC's bogus complaint about possible NULL in printf

Browse Source 
GCC started complaining that some of libbpf pr_warn() statements might
be passing NULL for map name. Map name is never NULL for non-NULL map
pointer, so this is a false positive which triggers build failures.
Silence format-overflow warning altogether to avoid this in the future
as well.
