Add ACL for media player USB devices

Originally we added an ACL for some particular mobile phone product IDs to
enable users to run e. g. the Android SDK as non-root. This was removed in
232f180 as we don't want to maintain product/vendor ID lists in udev.

However, we already know from media-player-info that devices like this are
media players. There is little reason to deny user access to those, so add back
a generic rule which adds an ACL to media player raw USB devices.
