[PATCH v2] ui/gtk: Register "Grab Input" shortcut to accel_group

[dongwon.kim@intel.com]

From: Dongwon Kim <dongwon.kim@intel.com>

The "Grab Input" shortcut key currently fails to trigger when the
window is in fullscreen mode because the menubar is hidden, which
disables GtkAccelMap-based shortcuts associated with it.

To ensure the accelerator remains active in fullscreen, connect it
directly to s->accel_group and explicitly set the hotkey display on
the menu item label.

v2: gd_accel_grab_input returns TRUE
