Complete translation to Norwegian bokmål
Translate remaining strings to Norwegian bokmål (nb). Also, cure previous translation of excessive anglicism and apply a more consistent use of actual Norwegian syntax.

newgidmap: enforce setgroups=deny if self-mapping a group
This is necessary to match the kernel-side policy of "self-mapping in a
user namespace is fine, but you cannot drop groups" -- a policy that was
created in order to stop user namespaces from allowing trivial privilege
escalation by dropping supplementary groups that were "blacklisted" from
certain paths.

This is the simplest fix for the underlying issue, and effectively makes
it so that unless a user has a valid mapping set in /etc/subgid (which
only administrators can modify) -- and they are currently trying to use
that mapping -- then /proc/$pid/setgroups will be set to deny. This
workaround is only partial, because ideally it should be possible to set
an "allow_setgroups" or "deny_setgroups" flag in /etc/subgid to allow
administrators to further restrict newgidmap(1).

We also don't write anything in the "allow" case because "allow" is the
default, and users may have already written "deny" even if they
technically are allowed to use setgroups. And we don't write anything if
the setgroups policy is already "deny".

The userdel checks for users with getpwnam() which might not work
properly in chroot. Check for the user's presence in local files only.
