PackageManager: fix app lib migration for device with /datadata

For devices using /datadata, dataPathString will point
to /datadata while nativeLibraryDir will point to /data/data.
Thus, compare to /data/data directly to avoid problems.

AudioService: Don't adjust volume when vol-downing to vibrate or silent

Pressing vol-down to vibrate or silent would (previously) still adjust the
stream volume, setting the last audible volume to 0, which is not allowed
for voice-capable devices.  Thus, the last audible volume would reset to
default on reboot if on vibrate/silent or the lowest volume setting.

By not adjusting volume when vol-downing to vibrate or silent on
voice-capable devices, the last audible volume is always preserved across
reboot.
