Yukihiro "Matz" Matsumoto 75738a350a mruby-bigint: fix memory leak in mrb_bint_lcm() ...

mpz_abs() internally allocates via mpz_init_heap(), so
pre-allocating abs_x/abs_y with mpz_init_temp() leaked the
original allocations. let mpz_abs() handle allocation directly.

also use divide-first formula (abs_x/gcd)*abs_y to reduce
intermediate product size, and add bint_norm() for the result.
