Move sgabios setup to hypervisor-ironic

This moves setup of sgabios ROM to the ironic hypervisor library.
This is failing to backport to juno because of an error in the sideways ironic
grenade. install_ironic() is expected to setup only python things and happens
earlier than initial package installation.
