gmputil: turn mpz_printf into mpz_vfprintf to restore --with-mini-gmp
2535ba7006f2 ("src: get rid of printf") uses gmp_vfprintf() which doesn't exists in mini-gmp.c, this breaks compilation with --mini-gmp. This patch implements poor man's gmp_vfprintf that takes one single argument which is what we need. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
