This variant seems to work:

  REMOTE_TEMPORARY_FILE_DIRECTORY=/plink:user <at> host:/tmp make lisp/net/tramp-tests

Most of the tests are "skipped", but the one you were interested in
isn't skipped, and indeed fails:

  Test tramp-test05-expand-file-name condition:
      (ert-test-failed
       ((should
	 (string-equal
	  (expand-file-name "/method:host:/path/.")
	  (if ... "/method:host:/path/" "/method:host:/path")))
	:form
	(string-equal "/method:host:/path" "/method:host:/path/")
	:value nil))
     FAILED  12/70  tramp-test05-expand-file-name (0.000000 sec)
