Revert message catalog compile

Change I26fac0ccf8fd4818e24618d56bf04b32306f88f6 brought in this
message catalog compile which is unrelated to the original issue.  I'm
assuming it is from a bad merge.  It creates issues because gettext
isn't installed on fresh systems (although in openstack infra it is
already there thanks to other dependencies).

Log early boot of Ironic VMs to serial with sgabios

This adds sgabios to the list of packages for Ironic and configures
the libvirt domain to redirect BIOS messages to serial via sgabios,
when console logging is enabled.  The sgabios package in Ubuntu
currently has an apparmor bug, so that is worked around here.

This allows visibility into early boot of Ironic nodes and should
help get to the bottom of a frequent failure we're seeing in the gate.

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.
