bug#55706: 29.0.50; files test fails about 20% of the time

[Lars Ingebrigtsen]

I can't reproduce this reliably, but in about 20% of the times I run
"make check", this test fails:

Test files-tests-file-name-non-special-file-in-directory-p condition:
    (ert-test-failed
     ((should
       (file-in-directory-p nospecial nospecial-tempdir))
      :form
      (file-in-directory-p "/:/tmp/files-testsuqfdq1.special" "/:/tmp/")
      :value nil))
   FAILED   52/112  files-tests-file-name-non-special-file-in-directory-p 
(0.001158 sec) at lisp/files-tests.el:692

Michael wrote the test, so I've added him to the CCs.
