libnftables: reallocate definition of nft_print() and nft_gmp_print()

They are not part of the libnftables library API, they are not public symbols,
so it doesn't not make sense to have them there. Move the two functions to a
different source file so libnftables.c only has the API functions.

I think copyright belongs to Phil Sutter since he introduced this code back in
commit 2535ba7006f22a6470f4c88ea7d30c343a1d8799 (src: get rid of printf).
