Subject: [PATCH] switcherPopup: Use roundtrip time when the popup is
 modifier-less

The noModsTimeout obviously finishes inside a timeout callback, which
means `global.get_current_time()` might return Clutter.CURRENT_TIME (ie.
0) when called inside it, because it's not called while handling an
event. This means when switching apps or activating a window, the
timestamp passed to `activate_window` may be 0, which is the reason why
the altTab switcher is currently broken when using modifier-less
keybindings.

Fix that by using `meta_display_get_current_time_roundtrip`, which
always return a valid timestamp, instead of
`shell_global_get_current_time`.
