boot: switch default menu key to ESC

On some platforms, F12 may be hard to access; for example, on OS X
machines F9-F12 have been intercepted by the OS for a long time, and
on newer OS X releases function keys are basically gone for good.

Which keys are and are not available depends on the client, not on
the server, but only function keys are usually trapped by terminals.
Hence, using ESC for the boot menu avoids the problems associated
with F12.
