xfree86: xf86Module.h: macro for declaring input driver module version

Reduce the effort of declaring/filling an input driver's module version
struct to short statement like this:

    XF86_MODULE_VERSION_INPUT("egalax",
                              PACKAGE_VERSION_MAJOR,
                              PACKAGE_VERSION_MINOR,
                              PACKAGE_VERSION_PATCHLEVEL);

This will create a properly filled XF86ModuleVersionInfo structure
named `modInfo`.
