Bump to semaphore-compat 2.0.1

[wz1000]

semaphore-compat-2.0.1 fixes a number of bugs in the semaphore-compat-2.0.0 implementation,
including some critical fixes on darwin, where semaphore-compat-2.0.0 was quite broken.

• Patches conform to the coding conventions.
• Any changes that could be relevant to users have been recorded in the changelog.
  • Is the change significant? If so, remember to add significance: significant in the changelog file.
• The documentation has been updated, if necessary.
• Manual QA notes have been included.
• Tests have been added. (Ask for help if you don’t know how to write them! Ask for an exemption if tests are too complex for too little coverage!)

Thank you.

Given that this has to be backported and that it affects changelogs, let's fast track it.
