Stop testing lower-constraints

[1] http://lists.openstack.org/pipermail/openstack-discuss/2020-October/018445.html

Conflicts:
  .zuul.yaml
  lower-constraints.txt

Changes:
  bindep.txt

NOTE(stephenfin): Conflicts are due to the changed job template (ussuri
vs victoria) and slightly different lower constraints between branches.
We also need to remove 'libffi6' from 'bindep.txt' since Focal doesn't
have this. This was done in the Victoria cycle as part of change
Iab3634039845adb649c7fd69d1812b405a61433c but we must squash it in here.
