Create a modified version of directdisk.wks that enabled legacy boot
images in Isar. "bootimg-pcbios-isar" expects the rootfs to contain the
packages "syslinux syslinux-common" and will create a disk using this
bootloader.

Issues:
1. wic was called under sudo
2. wic and its plugins can use sudo to do whatever they want
Impact:
Issue 1 is addressed, but Issue 2 has always been there and has come to
stay.

I still prefer the almighty big sudo, this patch adds complexity and is
a hack. But i also think that touching contrib code in _any_ way is so
evil that any hack should be considered to avoid it.
