libnftables: drop gmp_init() and mp_set_memory_functions()
Setting global handles for libgmp via mp_set_memory_functions() is very
ugly. When we don't use mini-gmp, then potentially there are other users
of the library in the same process, and every process fighting about the
allocation functions is not gonna work.
It also means, we must not reset the allocation functions after somebody
already allocated GMP data with them. Which we cannot ensure, as we
don't know what other parts of the process are doing.
It's also unnecessary. The default allocation functions for gmp and
mini-gmp already abort the process on allocation failure ([1], [2]),
just like our xmalloc().
Just don't do this.
