Remove File::Spec from t/TEST - VMS is fine without it. Win32 doesn't use it.

Also remove one complex alternation regexp, and replace it with a hash lookup.
At this stage do we trust the regexp engine that much?

[Really TEST shouldn't be relying on require working, and hence being able to
pull in modules to do essential parts of its work. And modules that rely on
OO dispatch - :-(]
