Use ``strings.TrimPrefix()`` for relative paths instead of ``strings.TrimLeft()``, since ``TrimLeft`` takes in a cutset instead of a prefix sub-string. In this particular case, if the ``--root`` (output) directory is ``/tmp/foo`` and we are determining the relative path for ``/tmp/foo/tmp-foo``, the relative path would result in ``/-foo`` since ``/tmp/foo/tmp`` would be matched by the ``/tmp/foo/`` cutset. This results in a flawed map of ``knownPaths`` inside slicer.go, which is only checked by the mutation script functions such as ``content.list()``. This commit fixes said bug.
