iommufd: Add missing IOMMUFD_DRIVER kconfig for the selftest

Some kconfigs don't automatically include this symbol which results in sub
functions for some of the dirty tracking related things that are
non-functional. Thus the test suite will fail. select IOMMUFD_DRIVER in
the IOMMUFD_TEST kconfig to fix it.
