nftutils: add and use wrappers for getprotoby{name,number}_r(), getservbyport_r()
We should aim to use the thread-safe variants of getprotoby{name,number}
and getservbyport(). However, they may not be available with other libc,
so it requires a configure check. As that is cumbersome, add wrappers
that do that at one place.
These wrappers are thread-safe, if libc provides the reentrant versions.
Use them.
