[PATCH] ui/cocoa: Do not raise keys before QEMU resigns active

[Akihiko Odaki <akihiko.odaki@gmail.com>]

ui/cocoa used to raise all keys before it resigns active to prevent a
stuck key problem caused by key up events it does not see while it is
inactive. The problem is solved by checking -[NSEvent modifierFlags] in
commit 6d73bb643aa725348aabe6a885ac5fb0b7f70252, which is better
because it handles the case that key *down* events are missed while it
is inactive.
