recovery: allow relabelto unlabeled and other unlabeled rules
The recovery script may ask to label a file with a label not
known to the currently loaded policy. Allow it.
Addresses the following denials:
avc: denied { relabelto } for pid=143 comm="update_binary" name="vdc" dev="mmcblk0p25" ino=212 scontext=u:r:recovery:s0 tcontext=u:object_r:unlabeled:s0 tclass=file
avc: denied { setattr } for pid=143 comm="update_binary" name="vdc" dev="mmcblk0p25" ino=212 scontext=u:r:recovery:s0 tcontext=u:object_r:unlabeled:s0 tclass=file
