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)

bootanimation: Only try to shutdown the mediaplayer if it was prepared

The bootanimation tries to shutdown the mediaplayer gracefully by waiting
on an asynchronous shutdown event for 5 seconds.

If, however, there is no boot sound, that asynchronous shutdown event will
never happen and the animation will be stopped for 5 seconds before shutting
down.

Visibly, this fixes the issue where the bootanimation would simply stop near
the end for exactly 5 seconds.
