[PATCH v6 RFC 06/10] kdrive: add options to set default XKB properties

[Laércio de Sousa]

This patch introduces convenient command-line options -xkbrules,
-xkbmodel, -xkblayout, -xkbvariant, and -xkboptions, to set default
values for these properties.

These options can be handful in cases where corresponding values can't
be taken from devices' udev properties, and compile-time default
values don't match user locale.
