gummiboot: WaitForKeyEx hanging patch
I recently ran into a Gummiboot bug where pressing any key on boot causes the
boot menu to respond to that key (e.g. moves the highlighted entry if I press
down-arrow) but subsequently freeze (booting proceeds without issue if no key
is pressed andthe auto-timeout passes).  

I found a virtually identical issue on gummiboot's "parent/fork" project
systemd-boot (systemd/systemd#3632), with an alleged fix that has been merged
(systemd/systemd#3735), so I made this PR to backport that patch to gummiboot.
