Add support for QC's time_daemon

Enabled by BOARD_USES_QC_TIME_SERVICES=true, it requires the device
to provide its own time_daemon executable and libtime_genoff.so
proprietaries. The library should be copied by the device's setup
config to $OUT/obj/lib for linkage (and pushed to the final build,
obviously)

SystemUI: Fix missing top task in recent panel.

If preloadRecentTasksList was not called or was called too
late and RecentsActivty already started and last top activity has
excludeFromRecents flag setted it might be missing
from recent application list.

Adjust KitKat easter egg to display "K" no matter what

The way is currently working, it pulls the first letter of the build_id for the easter egg. This is making it to where some devices show a "J" instead of a "K", the way it was meant to be.
