tests: fix checks for https-mtls proto

If there were two tests using the "https-mtls" server there was a perl
unbound variable error, since certfile wan't set. Additionally, once the
responsiveserver function was actually called, it failed finding a
responsiveness function. For now I made it use the `verifypid` function,
since the curl execution in `verifyhttp` doesn't know about client
certificates.

Closes #17493
