[pve-devel] [PATCH container] Setup: order fqdn before hostname in /etc/hosts

[Wolfgang Bumiller]

Some services seem to require this to lookup the local fqdn.
This only affects /etc/hosts while /etc/hostname still uses
the non-fqdn hostname.

This is also consistent with behavior in 4.0 (before commit
ce289e3c6e).

Fixes #845
