build.config.msm.gki: Add sanity check for ABI

Browse Source 
To help ensure that the GKI kernel and device kernel are kept in sync,
test whether abi_gki_aarch64.xml matches between the GKI kernel and
msm-5.10.

This check is not fail-safe however. If an ABI impacting change is
committed to either msm-5.10 or GKI tree without the corresponding ABI
update, then this check will incorrectly proceed. The correct way is to
do a full ABI comparison between msm-5.10 and the GKI tree with every
build, however that is time-intensive. Thus, prefer to do the simple
check for now.
