[pve-devel] [PATCH installer] network: sync option names with pve-common

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

back in 2018, commit 1accc6da659d8a02dcf1c2a636749e6f48fb9c2d
"Inotify : write network config : use modern syntax for options"
changed pve-common's /etc/network/interfaces writer to prefer options
with '-' over those with '_'.

having the installer write the old variant makes any modification of the
vmbr0 interface via the API also change these three lines to the new
variant - so let's do it right from the start.
