Yukihiro "Matz" Matsumoto 5ed0cd4ecb bigint.c: increase karatsuba scratch allocation safety margin ...

the previous fixed safety margin of 8 limbs was insufficient for certain
edge cases involving deep recursion levels in karatsuba multiplication,
as discovered by oss-fuzz. changed to proportional margin (~12.5% plus
fixed overhead of 16) that scales with input size.

this prevents potential buffer overruns in deeply nested karatsuba
multiplications while maintaining efficiency for typical cases.
