i18n: do not use systemd-vconsole-setup

systemd-vconsole-setup was not designed to be run from udevd.
It checks locale environment to decide, whether UNICODE should
be enabled or disabled. Normally environment is setup by
systemd; but the only environment available in udev rules is
those from device properties. It means systemd-vconsole-setup
always assumes default C locale and disables UNICODE.

Revert to using built-in console_init which explicitly
imports locale settings from /etc/vconsole.conf. Alternative
is to revert 6545b9d7 and call console_init directly :)

Additionally patch fixes console_init to use new namespace as
well as ensures that default font is always installed.
