[efi] Work around broken UEFI keyboard drivers

Some UEFI keyboard drivers are blissfully unaware of the existence of
either Ctrl key, and will report "Ctrl-<key>" as just "<key>".  This
breaks substantial portions of the iPXE user interface.

Work around these broken UEFI drivers by allowing "ESC <key>" to be
used as a substitute for "Ctrl-<key>".
