Provide an alternate command-line flag for timeout in run-webkit-tests
https://bugs.webkit.org/show_bug.cgi?id=202758
<rdar://problem/56124032>

Reviewed by Tim Horton.

I always get the flag "--time-out-ms" wrong.
Everywhere else we use the single-word version of "timeout", including
the documentation for --time-out-ms!

Add an alternate that is just "--timeout", and update the documentation
to mention it is measured in milliseconds.
