DOC: compression: Update the reasons for disabled compression

- Update the list of status codes to include 201 - 203.
- Remove the fact about the temporary workaround for chunked responses
  (this is verified using reg-test compression/h00000.vtc).
- Add malformed ETags

This commit should be backported together with b229f018eedef4d18571ce6da23d8e153249a836
the changes should be correct until 1.7 at the very least, possibly older.
