Lennart Poettering 116687f267 resolved: read DNS conf also from creds and kernel cmdline
Note that this drops ProtectProc=invisible from
systemd-resolved.service.

This is done because othewise access to the booted "kernel" command line is not
necessarily available. That's because in containers we want to read
/proc/1/cmdline for that.

Fixes: #24103
