cleanup temporary file usage in tests

mktemp(1) requires files to end with "XXXXXXXX", not just have
that template anywhere.  Also, add pid files to the TEST_RM_LIST
since test failures can leave a pid file dangling.  Lastly,
since the config.ru files are 100% static, just check them
as standalone files in instead of allocating a tempfile on them
for easier maintenance.
