build: support older GMP versions
The new factor code introduced usage of mpz_inits() and
mpz_clears(), which are only available since GMP >= 5,
and will result in a compile error when missing.
* m4/gmp.m4 (cu_GMP): Define HAVE_DECL_MPZ_INITS appropriately.
* src/factor (mpz_inits): New function, defined where missing.
(mpz_clears): Likewise.
