Read build.prop file when provided in AVD.

Ensure that the build.prop is read for both platform builds
and AVDs, this helps ensure that the right target CPU ABI is

This fixes an issue where an ARMv7-A based system image / kernel
might be mistaken for an ARMv5TE one. The end result being the
inability to properly boot the kernel.
