Use XK_ANY_MOD instead of XK_NO_MOD in key definition

Use XK_ANY_MOD instead of XK_NO_MOD in key definition

Usually terminal emulators don't generate any sequence for a combination
they don't have registered, for example Shift + Next, but st behavior
previous to the keyboard patch generates the sequence without the modifier,
in this example Next. This patch uses the XK_ANY_MOD in order to get this
same behaviour.
