autotest: Remove screenshot test from WindowManagerHotkeys.
I'm making the window manager write logged-in screenshots to
/home/chronos/user/Downloads instead of
/home/chronos/user/Downloads/Screenshots. I don't see much
value in continuing to test the screenshot hotkey here --
there's already another test for Ctrl-Alt-T.
BUG=chromium-os:16883
TEST=still passes
