hax: add Darwin support

Re-add the MacOSX/Darwin support:
Use the Intel HAX is kernel-based hardware acceleration module
(similar to KVM on Linux).

Based on the original "target/i386: Add Intel HAX to android emulator" patch
from David Chou <david.j.chou@intel.com> from  emu-2.2-release branch in
the external/qemu-android repository.
