[PATCH 2/6 v2] libdrm: Android.mk: Add minimal Android platform check

[John Stultz]

Add a check to error out on Android version K(4.4) or
lower.

This is due to dependency added in a previous commit on mmap64,
which was introduced with Android L.

NOTE: This change was suggested by Emil, and I've implemented
it as suggested, but due to the fact that the Android.mk files
are no longer usable with AOSP/master, I'm not able to test
this change. Help in validating would be appreciated.
