input: don't reset the XKB compose state in keymap()

Browse source 
When the compositor sends a new keymap, don't reset the XKB compose
state.

This is done by initializing the XKB context, along with the compose
state, when binding the seat, instead of in keymap().

Then, in keymap(), simply stop destroying the old xkb state. Only
destroy, and re-create the keymap state.
