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.

keyguard: fix layout for 320dp devices

800x480px dpi devices have less screen space than the xhdpi devices
Google designed the layout for and the layout needs adjustment.

- Reduce the lockscreen security container size such that the clock
  widget has enough space to display its content.
- In the SIM PIN/PUK view, Google put an empty widget on top, but
  we don't have space for that, increase its size such that the
  widget practically disappears.

This should not have any effect on devices with larger screens.
