Yukihiro "Matz" Matsumoto 06d6d0b0a5 bigint.c: fix memory leak in powm with oversized modulus ...

Barrett and Montgomery reduction compute 2^(2k) internally where k
is the modulus bit length. When this exceeds MRB_BIGINT_BIT_LIMIT,
mrb_raise() via longjmp skips cleanup of allocated temporaries.
Add early modulus size check before any heap allocation.
