xdriver_x86-input-joystick: Install server config

In order for joysticks to be detected and used with this
driver, we need an xorg-server configuration file. This commit
installs such conf file to the default X11 xorg.conf.d path,
so we can at least provide a working template.

Users with specific needs can of course override it.
