Make TestLib::perl2host more consistent and robust

Sometimes cygpath has been observed to return a path with a trailing
slash. That can cause problems, Also, make "cygpath" usage
consistent with "pwd -W" with respect to the use of forward slashes.

Backpatch to release 14 where the current code was introduced.
