gnu: fio: Don't bother wrapping scripts.

fio comes with many scripts of varying utility.  Some require extra additional
programs, which users can easily install as needed; there is little use in
imposing all optional dependencies on all users of fio.

* gnu/packages/benchmark.scm (fio)[arguments]: Remove patch-paths phase.
Rewrite move-outputs to move all discovered scripts and not wrap any.
[inputs]: Remove GNUPLOT, PYTHON-2, PYTHON2-NUMPY, and PYTHON2-PANDAS.  Add
PYTHON.
