Fix two failing tests in mh-utils-tests

* test/lisp/mh-e/mh-utils-tests.el
(mh-test-utils-mock-call-process): Add mock for root folders.
(mh-folder-completion-function-08-plus-slash)
(mh-folder-completion-function-09-plus-slash-tmp): Skip these tests
with Mailutils, which doesn't handle root folders.  (Bug#51902)
