Fix compilation warning in pcmpl-gnu.el

* lisp/pcmpl-gnu.el (pcomplete/tar): Remove binding of
pcomplete-suffix-list, because it's not consulted in any of the
functions called here, and has had no effect since 2011.  If we
want to support not inserting a space after the = sign, we have to
implement that, but it's not currently done.
