nfc: allow sending bugreports via nfc
Same change as 9819a6 but for nfc.
Nfc can receive bugreport data for beaming to another device.
This comes across as an open file descriptor. Allow nfc access
to bugreports.
Addresses the following denial:
avc: denied { read } for path="/data/data/com.android.shell/files/bugreports/bugreport-2015-03-30-04-49-57.txt" dev="mmcblk0p27" ino=82334 scontext=u:r:nfc:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file op_res=-13 ppid=435 pcomm="main" tgid=23475 tgcomm="m.android.shell"
