Revert "Resolve issue with test_harness and nmake"

This reverts commit d2370755aef6209efc394332a70e81ac3a648768.

Whilst this fixed the problems with nmake it broke a whole bunch
of other things.

Interestingly changing t/*.t to t\*.t also resolved the problem
with nmake.

Also removing the quotes from around the FULLPERL did too.
