Resolve #2627 CNG: UBI Containers - LIBDIR not defined for users who do not use our build image

Closes gitlab-org/charts/gitlab#2627

See merge request gitlab-org/build/CNG!648

Update ubi builder Dockerfile LIBDIR entry to specify a default but allow override by existing ENV variable

`ActiveRecord::ConnectionHandling.postgresql_connection(config)` will
emit `ActiveRecord::NoDatabaseError` when `PG::Error` includes the name
in `production.database` of `database.yml`. This is to indicate a
problem accessing the database shema, but not the database server.

This error is silenced by `ActiveRecord::MigrationContent.current_version`
which results in a `nil` return. This `nil` is not the same as `0`, and
needs to be treated differntly, as it indicated that we could not
determine the version of the schema within the database, because we were
unable to access the configured database name.

gitlab-rails: remove ee/spec/ if present

See merge request gitlab-org/build/CNG!659
