Remove from blkid, blkid_untrusted, fsck, fsck_untrusted, sdcardd and
sgdisk.
Tested by adding external sdcard with and without
"adb shell sm set-force-adoptable true" command.
Address the following denials:
avc: denied { read } for name="swaps" dev="proc" ino=4026536590 scontext=u:r:fsck:s0 tcontext=u:object_r:proc:s0 tclass=file
avc: denied { open } for path="/proc/swaps" dev="proc" ino=4026536590 scontext=u:r:fsck:s0 tcontext=u:object_r:proc:s0 tclass=file
avc: denied { getattr } for path="/proc/swaps" dev="proc" ino=4026536590 scontext=u:r:fsck:s0 tcontext=u:object_r:proc:s0 tclass=file
avc: denied { read } for name="filesystems" dev="proc" ino=4026536591 scontext=u:r:blkid:s0 tcontext=u:object_r:proc:s0 tclass=file
avc: denied { open } for path="/proc/filesystems" dev="proc" ino=4026536591 scontext=u:r:blkid:s0 tcontext=u:object_r:proc:s0 tclass=file
avc: denied { getattr } for path="/proc/filesystems" dev="proc" ino=4026536591 scontext=u:r:blkid:s0 tcontext=u:object_r:proc:s0 tclass=file
