Settings: Add CM PlatLogo & CMCaseView (1/2)

* Based on Danesh M commit from 10.1
* Always use "K" letter for android version easter egg since
  some devices override BUILD_ID and the letter "J" appears instead of "K"
* Add some padding (left & right) to the PlatLogo if the width of the
  PlatLogo is bigger tham the actual device width
* Added CM mascot drawables

ActivityManager: Fix monkey tests

Change I30e38c6c27d339d55a8f9a0f4106185356a9b9a0 (adding ordered
broadcast prioritization) adds the assumption that every broadcast
generator has a full-fledged caller app, which isn't true for
monkey-created tests. Make sure the caller is a full app before
checking if it is AID_SYSTEM to avoid an NPE

Fixes com.android.cts.monkey.*
