bash-completion: fix syntax error

There is a syntax error in a redirection:

  $ bash -x utils/ipset_bash_completion/ipset
  + shopt -s extglob
  utils/ipset_bash_completion/ipset: line 365: syntax error near unexpected token `('
  utils/ipset_bash_completion/ipset: line 365: `done < <(PATH=${PATH}:/sbin ( command ip -o link show ) )'

Move the environment variable assignment into the sub-shell.
