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]

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