bootfiles, vc-graphics: consolidate SRC_URI and S variables

The variables RPIFW_SRC_URI and RPIFW_S are created in the common firmware
include file so that it is easier to override the firmware source in a local or
distro config file. RPIFW_SRC_URI is used to set SRC_URI in firmware.inc as it
is common to both bootfiles and vc-graphics. RPIFW_S is used as a prefix for S
in bcm2835-bootfiles.bb and vc-graphics.inc as different subdirectories are
referenced in each recipe.
