[PATCH v2 9/9] ci: run reference binaries against current ABI

[David Marchand <david.marchand@redhat.com>]

Let's check if a testpmd and unit tests from a reference build can run
with the current release libraries/drivers.

This gives another level of ABI checking, like catching regressions on
experimental or internal ABI symbols that get promoted to stable.

We may need to skip unit tests that were added since the reference.
So add a ABI_SKIP_TESTS environment variable in preparation.

Changes since v1:
- dropped hack, testing this patch can't be done in the CI now,
- emptied the excluded tests list,
- added test-null.sh,
