[PATCH nft] src: use printf() instead of pr_debug() whenever possible

[Pablo Neira Ayuso <pablo@netfilter.org>]

pr_debug() is disabled with --with-mini-gmp since it relies on the
gmp_printf(), which is not available in the mini-gmp implementation.
Use printf() instead of pr_debug() if no mpz_t types are used, so
we get debugging information for proto-ctx as well.

This leaves the pr_debug() usage limited to src/segtree.c.
