[PATCH ipset 2/2] bash-completion: restore fix for syntax error

[Jeremy Sowden <jeremy@xxxxxxxxxx>]

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 ) 2>/dev/null)'

Move the environment variable assignment into the sub-shell.

This fix was previously applied in commit 417ee1054fb2 ("bash-completion:
fix syntax error"), but then reverted, presumably by mistake, in commit
0378d91222c1 ("Bash completion utility updated").

Fixes: 0378d91222c1 ("Bash completion utility updated")
