[PATCH weston v2 1/3] toytoolkit: Allow operation without a keymap

[Rob Bradford]

From: Matt Roper <matthew.d.roper at intel.com>

In preparation for upcoming changes, we want to make sure that apps
written with the toy toolkit continue to operate properly if no XKB
keymap is received.  If there's no XKB keymap, then we shouldn't
try to figure out keyboard modifier states (since we probably don't
even have equivalents of PC-style modifiers).
