Ubuntu: CI: rely on os_distribution, remove interfaces pause

We can now rely on the os_distribution variable to set sensible defaults
for Ubuntu. It is set automatically in kayobe-config-dev.

The interfaces pause workaround is no longer required since switching to
systemd-networkd.

Depends-On: https://review.opendev.org/c/openstack/kayobe-config-dev/+/788475
