Recovery-persist now parses the file /cache/recovery/last_install; and
unlinks it after reporting metrics. Sets up the permission accordingly;
also grants access to /cache if it's a symlink (useful for a/b devices.)
Denials:
recovery-persis: type=1400 audit(0.0:7): avc: denied { write } for name="recovery"
dev="sda35" ino=5275650 scontext=u:r:recovery_persist:s0
