[PATCH] ipset: Fix syntax error of bash completion in Debian environment

[Neutron Soutmun <neo.neutron@gmail.com>]

Debian packaging tool (lintian) warns the syntax error of bash completion
as it uses the extglob shell option that should be run in
the ** #!/usr/bin/env bash ** and the shell option set should be moved to
global scope.
