The original rationale for this was to make sure that if
lxcpath was /home/serge/lxcbase, then then lockdir
(/run/user/serge/lock/lxc/home/serge/lxcbase) would be
owned by the same user as /home/serge/lxcbase.

The only user who can chown to other uids (without CAP_CHOWN
added to fP) is root, who shouldn't be mucking with non-root
owned containers anyway.  In the meantime this causes a bunch
of noise for arguably no benefit.
