Subject: [PATCH] Only install low level keyboard hook if GTK_CSD=1

Added in eece8a7dd2405f76829031f3d6dd5e39fb5dc542 in order to
intercept keyboard combos to provide AeroSnap-like functionality for
CSD windows.

Unfortunately it causes many issues, e.g.
- https://gitlab.gnome.org/GNOME/gtk/issues/2015
- https://gitlab.gnome.org/GNOME/gtk/issues/1082
- https://gitlab.gnome.org/GNOME/gtk/issues/1033

As the hook is completely useless for non-CSD windows, only install
it if CSD is explicitly requested (environment variable GTK_CSD=1).
