Fix mediacodec on vndk-27

Browse Source 
Since android-10.0.0_r37, mediacodec seccomp policy now has two
includes. In AOSP 8.1, minijail is vendor-side.
AOSP 8.1's minijail has a bug, which can't read multiple includes.
All of this together means mediacodec is broken.

This fixes it by overriding vendor's minijail to a working one, in the
hope that vendors didn't change anything in their own minijail
