Allow adbd and app domains to read the symlink at /mnt/sdcard. This symlink was suppose to have been removed in the Gingerbread time frame, but lives on. Read access for this symlink was removed from adbd and the shell user in8ca19368da, and from untrusted_app incbf7ba18db. Addresses the following denials: avc: denied { read } for name="sdcard" dev="tmpfs" ino=9486 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:tmpfs:s0 tclass=lnk_file permissive=0 avc: denied { read } for pid=4161 comm=73657276696365203137 name="sdcard" dev="tmpfs" ino=5114 scontext=u:r:adbd:s0 tcontext=u:object_r:tmpfs:s0 tclass=lnk_file permissive=0 Bug: 25801877 Bug: 28108983 Change-Id: Ia31cd8b53c9c3a5b7d11be42c2fde170f96affb0
