dracut-functions: add additional drivers in host-only mode, too

this makes dracut load kernel module specified in add-drivers even
if building an host-only mkinitrd, it is useful in cases where we
might change some storage drivers and still don't want to build
an enormous initrd (e.g. ahci/ata_piix)
