btrfs-progs: Add Android build mk file

Add Android.mk to use btrfs on android device.

There are still outstanding problems and build support is incomplete:

1) phread_cancel was changed to pthread_kill due to android didn't
   support that.
2) This module needs lzo library on android/external folder.
3) blkid library doesn't support fully. So have to use -f option to
   work.
