[nft PATCH 1/2] main: Flush output from nft_gmp_print()

[Phil Sutter <phil@nwl.cc>]

This adds a missing call to fflush() to nft_gmp_print() just like in
nft_print(). This is strictly not necessary since usually
nft_gmp_print() is followed by a call to nft_print() but better not rely
upon this assumption.
