/proc, /sys access from uncrypt, update_engine, postinstall_dexopt
New types:
1. proc_random
2. sysfs_dt_firmware_android
Labeled:
1. /proc/sys/kernel/random as proc_random.
2. /sys/firmware/devicetree/base/firmware/android/{compatible, fstab,
vbmeta} as sysfs_dt_firmware_android.
Changed access:
1. uncrypt, update_engine, postinstall_dexopt have access to generic proc
and sysfs labels removed.
2. appropriate permissions were added to uncrypt, update_engine,
update_engine_common, postinstall_dexopt.
