ng_ipacct VIMAGE option on 12.1-RELEASE

[Eugene Kazarinov]

Hi.
Please change in pkg base default option on FreeBSD-12.1 to
VIMAGE enabled
because each time I do `pkg upgrade` it tries to reinstall ng_ipacct with
VIMAGE DISabled.
====
Installed packages to be REINSTALLED:
        ng_ipacct-20180401 (options changed)
====

After that I must do
pkg deinstall ng_ipacct-20180401
cd /usr/ports/net-mgmt/ng_ipacct
make install clean

And I cant dont reinstall ng_ipacct than pkg upgrades all other packages.

Thank you.
