maybe fix sdcardd SELinux denial.

The setup for /data/media on flounder is inconsistent with
every other device. Make consistent.

Maybe addresses the following denials:
<5>[  438.978714] type=1400 audit(947695523.619:15): avc:  denied  { write } for  pid=197 comm="sdcard" name="0" dev="mmcblk0p25" ino=553793 scontext=u:r:sdcardd:s0 tcontext=u:object_r:system_data_file:s0 tclass=dir
<5>[ 3474.016356] type=1400 audit(947698558.659:27): avc:  denied  { open } for  pid=197 comm="sdcard" path="/data/media/0" dev="mmcblk0p25" ino=553793 scontext=u:r:sdcardd:s0 tcontext=u:object_r:system_data_file:s0 tclass=dir
