This adds support for "templates" source.properties files that can
inherit the platform version/codename/api level from the build.
The purpose is for a given build to always generate SDK files that
match the platform generated in the same branch.

This patch depends on https://review.source.android.com/24052
It is used to ensure that the proper kernel image is copied to the
platform image's kernel-qemu.
This is needed because for ARMv7 platform builds, the image is
in prebuilt/android-arm/kernel/kernel-qemu-armv7, instead of
prebuilt/android-arm/kernel/kernel-qemu
