kitty kbd: switch from GTK to XKB mode for 'consumed' modifiers

Browse source 
This fixes an issue where some key combinations resulted in different
output (e.g. escape code vs. plain text) depending on the state of
e.g. the NumLock key. One such example is Shift+space. Another example
is Shift+BackSpace.

This patch also removes the hardcoded CapsLock filter, when
determining whether a key combo produces text or not, and instead uses
the locked modifiers as reported by XKB.
