Add WAIT screen to default bitmap

Some systems take a long time to program the EC firmware (because it's
behind a really slow I2C bus or something). This could happen at any boot as
part of software sync. If it's necessary to reprogram the EC on a slow
system, we need to display a BIOS screen to the user so he/she doesn't think
it's bricked.

This CL is just to add a new default bitmap so we'll have something to
display when we need it. Nothing actually uses it yet.

BUG=chrome-os-partner:12254
TEST=none

There should be no user-visible changes. We don't invoke this screen yet.
