Add better support for keymap update handling

Use the new X11 support API xkb_x11_* released in libxkbcommon version 0.4.0.

From the commit message where this API was introduced:

"These are function to create an xkb_keymap directly from XKB requests
to the X server. This opens up the possibility for X clients to use
xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for
keyboard support.

Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES
property? This does not account for custom keymaps, on-the-fly keymap
modifications, remote clients, etc., so is not a proper solution in
practice. Also, some servers don't even set it. Now, the client just
needs to recreate the keymap in response to a change in the server's
keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends)."

This patch moves XKEYBOARD presence decision from compile time to runtime
for a proper remote X client support.
