DO NOT MERGE: Make bluetooth, nfc, radio and shell adb-installable

bluetooth, nfc, radio and shell are not explicitly declared
in installd.te. This prevents applications in those group
from upgrading by "adb install -r".

You can reproduce the issue by following step:
 1. adb pull /system/priv-app/Shell.apk
 2. adb install -r Shell.apk
 3. install failed with the error log blow

[Error in logcat]
E/installd(  338): couldn't symlink directory '/data/data/com.android.shell/lib' -> '/data/app-lib/com.android.shell-1': Permission denied
E/installd(  338): couldn't symlink directory '/data/data/com.android.shell/lib' -> '/data/app-lib/Shell': Permission denied

[Error in dmesg]
<5>[  112.053301] type=1400 audit(1387412796.071:10): avc:  denied  { create } for  pid=337 comm="installd" name="lib" scontext=u:r:installd:s0 tcontext=u:object_r:shell_data_file:s0 tclass=lnk_file

This operation fails only if the app belongs to any of the
groups specified in the commit title.

DO NOT MERGE: Adding permissions needed to remove cache

During removing cache data using Zipper application, I found violation logs.

avc:  denied  { write } for  pid=198 comm="installd" name="cache" dev="mmcblk0p29" ino=81680 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=dir
avc:  denied  { remove_name } for  pid=198 comm="installd" name="downloadfile.apk" dev="mmcblk0p29" ino=82247 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=dir
avc:  denied  { unlink } for  pid=198 comm="installd" name="downloadfile.apk" dev="mmcblk0p29" ino=82247 scontext=u:r:installd:s0 tcontext=u:object_r:download_file:s0 tclass=file

Reproduction path is like below
1. Downloading Zipper application from Google Play (I used Zipper 1.9.9.2)
2. Clicking option and clicking "removing cache" button
