Newuidmap/newgidmap binary is missing

I get this warning all the time

lxc postgres-test 20220813095934.265 WARN conf - …/src/src/lxc/conf.c:lxc_map_ids:3592 - newuidmap binary is missing
lxc postgres-test 20220813095934.265 WARN conf - …/src/src/lxc/conf.c:lxc_map_ids:3598 - newgidmap binary is missing

despite I have these binaries installed

which newuidmap newgidmap
/usr/bin/newuidmap
/usr/bin/newgidmap

That’s fine. We purposefully don’t include those binaries in the LXD snap.
LXC knows how to set things up without those binaries and we don’t want to get into conflicts with the various distro configurations so are avoiding using newuidmap/newgidmap.
