[PATCH xinput] Announce support for XI 2.0 to the server.

[Peter Hutterer]

Technically, we're required to announce support for XI 2.0 through
XIQueryVersion. The behaviour of XI2 for clients that have not done so is
undefined, it just happened to work so far.

With XI 2.1 on the horizon, this may change so make sure we're clamining our
version correctly.
