  conf: allow writing uid mappings with euid != 0

In case unprivileged users run containers via execute() or a start*() there are
valid cases where they may only want to map their own {g,u}id. Let's not block
them from doing so by requiring geteuid() == 0.

When we didn't create a net dev we should make sure that we don't delete it.  We

Closes #1600.
