bootb: in uloader, use a shorter timeout and Ctrl-X instead of Ctrl-C.

We virtually never want to interrupt the uloader, but aren't quite
confident enought o say "never" yet, so just use the shortest timeout that's
humanly possible.

Also, use a different interrupt character than the Ctrl-C used in the main
barebox, so that "just keep whacking Ctrl-C" is a viable option to interrupt
the normal boot process without accidentally interrupting uloader instead.
