[PATCH] ci: remove outdated default reference tag for ABI

[Thomas Monjalon]

The variable REF_GIT_TAG is set in the CI configuration
like .travis.yml or .github/workflows/build.yml.
The default value is outdated and probably unused.
It is removed completely to avoid forgetting an update in future.
