Use UPPER_CONSTRAINTS_FILE to deal with ipa-builder

The generate_upper_constraints.sh script in ipa-builder 2.2.0 still uses
UPPER_CONSTRAINTS_FILE as fallback to get the upper constraints file.

Also remove duplicate option in ironic-ipa-dib-base and use bionic for
the tinyipa jobs so we're sure to use the correct kernel when building
the ipa ramdisk.
