[pve-devel] [PATCH container] fix #3313: recover unprivileged bit from old config during pct restore

[Oguz Bektas]

since pct defaults to privileged containers, it restores the container
as privileged when `--unprivileged 1` is not passed.

instead we should check the old configuration and retrieve it
from there.

this way, when one creates an unprivileged container on GUI, it will be
still restored as unprivileged via pct (without having to pass
`--unprivileged 1` parameter)
