Optimize chrontel driver for wm bogus_screen_resize use flag
The bogus_screen_resize use flag is passed to the chromeos window
manager to cause it to clear unused areas of the screen when the
chrontel driver passes a (fake) resize event on the root window.
If running with this use flag, which the ebuild turns in to
-DBOGUS_SCREEN_RESIZE, then the driver does not need to put up
the black window for clearing the screen. This removes the messy
wipe effect that happens today.
The window manager fix also makes the login/lock screen work better.
BUG=chrome-os-partner:4380
TEST=gmerge to device, plug in 5:4 monitor check screen clears
