Fix broken bignum to int_ptr_t conversion.

This one affects all platforms. The extra sign check and
negation cancels out the one done in mp_get_uintptr, causing a
positive value for a negative input value.

* mpi/mpi.c (mp_get_intptr): Just coerce the uint_ptr_t
result to int_ptr_t.  That has the right semantics under
that the bits are preserved (under two's complement, in every
compiler I've ever used).  The unsigned value from
mp_get_uintptr already looks like the image of a two's
complement value.
