Implement __gnu_[u]ldivmod_helper methods in libc

These symbols were previously provided by Android's out-dated libgcc,
but they're removed/deprecated in upstream libgcc, and also won't be
available in libclang_rt.builtins. We need to provide these methods in
libc itself for compatiblity.

Test: build with these symbols stripped in libgcc
