Allow drmserver and mediaserver to read apk files.
Required to support passing resources via open apk files over Binder.
Resolves denials such as:
avc: denied { read } for pid=31457 comm="SoundPoolThread" path="/mnt/asec/au.com.shiftyjelly.pocketcasts-1/pkg.apk" dev="dm-10" ino=12 scontext=u:r:mediaserver:s0 tcontext=u:object_r:asec_apk_file:s0 tclass=file
avc: denied { read } for pid=31439 comm="Binder_2" path="/mnt/asec/au.com.shiftyjelly.pocketcasts-1/pkg.apk" dev="dm-10" ino=12 scontext=u:r:drmserver:s0 tcontext=u:object_r:asec_apk_file:s0 tclass=file
We do not allow open as it is not required (i.e. the files
are passed as open files over Binder or local socket and opened by the
client).
