resolve: Remove __res_context_query alloca usage
The bufsize on current Linux build is:
size_t bufsize = (type == 439963904 ? 2 : 1) * (12 + 4 + 255 + 1);
So with upper bound as 544 (2 * (12 + 4 + 255 + 1)). However, it might
increase to 2 * PACKETSIZE later with malloc. The default scratch_buffer
should fullfill the most usual allocation requirement.
Checked on x86_64-linux-gnu and i686-linux-gnu.
