Subject: [PATCH] login: fix close_range() use

This new syscall comes with three arguments (see kernel commit
278a5fbaed89dacd04e9d052f4594ffd0e0585de). Not sure why util-linux
assume only two.

Upstream-Status: Backport [https://github.com/karelzak/util-linux/commit/b8d99a618baffb4fc03cda4c40e29778b6d77ad4]
