build: Cleanup CPU-specific optimizations

 * TARGET_ARCH_CPU_VARIANT was a Linaro thing. Now that Android
   introducted TARGET_CPU_VARIANT, we should use this instead.
 * Added CFLAGS for Krait and Scorpion after the cleanup.

roomservice: Include forked repositories in device search

The github api defaults to not including forked repos in search results.
This causes roomservice to fail to find a device repo if it is a fork (I.E. maguro).
This commit adds the necessary argument to include forked repositories in the results
and fixes maguro syncing.
