mediaserver: allow loading shared library with text relocation
Bionic commit 8fdb3419a51ffeda64f9c811f22a42edf9c7f633 modified how we
handle shared libraries with text relocations, which triggered
an execmod denial when handling /system/vendor/lib/libmmjpeg.so.
Allow the mediaserver process to load shared libraries with text
relocations.
STEPS TO REPRODUCE:
1.Flash and Factory wipe the device.
2.Launch Camera.
3.Capture image tapping on shutter button and observe.
4.Then try to switch to video mode and observe.
OBSERVED RESULTS:
Shutter button gets disabled on capturing a picture and then
switching to video mode displays 'Can't connect to camera error'
EXPECTED RESULTS:
Camera should work without any error.
Addresses the following denial:
avc: denied { execmod } for path="/system/vendor/lib/libmmjpeg.so" dev="mmcblk0p25" ino=1734 scontext=u:r:mediaserver:s0 tcontext=u:object_r:system_file:s0 tclass=file
