[PATCH v3 4/8] image: Avoid breaking the build when mounts are no longer present on umount

[Anton Mikanovich <amikan@ilbers.de>]

From: Jan Kiszka <jan.kiszka@siemens.com>

This does not seem to trigger yet because we always have those
mountpoints present. But if that is no longer the case, we will bail out
when mountpoint fails due to the set -e.

Fixes: 165519a7b314 ("sudo: Fail on the first error")
