main: clean up handling of metacity keybindings during grabs

Although certain keys (like Ctrl-Alt-Tab and Alt-F2) should work in
the overview, we generally don't want them to work from inside each
others grabs. In particular, typing Left or Right from inside
Ctrl-Alt-Tab should navigate among focus groups, not switch
workspaces.
