Bstgen benchmarking test fails due to buildstream changes

Context

After reviewing https://gitlab.com/BuildStream/benchmarks/-/jobs/265575542 in raw form it would seem that the bstgen test is failing due to "RecursionError: Dependency depth is too large. Maximum recursion depth exceeded."

Discussions with project suggest that changes under BuildStream/buildstream!1449 (merged) mean that the bstgen project generated during the test is too recursively deep and that the failure is now expected.

As such it is expected that this test will need to be retired and replaced with another test eventually.

Task Description

Describe the steps to take / implementation plan. If it's a bug, do you know how it may be tackled?

• Remove bstgen test.

Acceptance Criteria

Test should be removed.
