Subject: Handle plugged memory leak from popt

With popt version 1.19, a memory leak was plugged. gdisk (sdisk) assumed
the value returned by poptGetArg() would remain usable forever because
popt has leaked the value for quite a long time.

This patch consist of one incomplete fix, that has been included in the
official repository, and one that of this writing, is still an open PR.
