Use ../../perl instead of ../../t/perl on Win32, as the latter doesn't work.

There seems to be some problem when paths that contain a directory named t are
make absolute, then fed to the command shell to be executed. I'm suspicious
that \t is getting interpolated as a tab by something, but there is no
confirmed diagnosis yet.
