v86d: fix for systemd to load uvesafb module correctly

The /etc/init.d/fbsetup script doesn't have any effect in a systemd
image. Its purpose is to load the uvesafb kernel module at boot.
This functionality could be achieved by adding a configuration file
under /etc/modules-load.d/ directory which would be parsed by the
systemd-modules-load.service.
