app.te: enable mapping ART apexdata cache executable
Some jars, such com.android.location.provider.jar, are both on the
system_server classpath and loaded as libraries. If the .oat files are
in the ART apexdata cache (due to being system_server classpath), they
need to be execute permission to be usable as AOT compiled libraries.
Bug: 184881321
Test: install an updated ART apex, open apps, see no more denials
