This patch changes 'framebuffer_app.inc' for the use of the depot. It
also fixes a few minor issues (e.g., the rtc config) found while testing
the various run scripts that use 'framebuffer_app.inc'.
Without the assignment of CPU quota, the priority definitions remain
without effect on base-hw, which may lead the USB driver on the
Raspberry Pi to get stuck in the presence of a time-consuming
application.
