[Qemu-trivial] [PATCH] Unbreak -no-quit for GTK when SDL is disabled

[Peter Wu]

When QEMU is built without SDL support, -no-quit would print an error message
that SDL is disabled. Since GTK also supports -no-quit, enable the option when
GTK or SDL is enabled at compile time.

While at it, do not create the no_quit variable when it is not used.
