ci: remove stale submodules after checkout

When ‘fetch’ strategy is used, Gitlab removes untracked files before
checking out new revision. However if the new revision doesn’t
include some of the submodules which were present in the old
revision, such submodule directories would not be removed by the
checkout. This extra step ensures that these stale submodules are
removed.
