The "fixup_uca" was recently renamed in DevStack to "fixup_ubuntu"
as part of https://review.opendev.org/#/c/619562 and that broke our
functional gate setup. The functional itself does not seeing to be
needed anymore (functional tests passes without it) so this patch is
getting rid of it to avoid another renaming in the future.
