Tests: gzip 410 Gone responses

Proposed changes

Add test coverage for gzip compression of 410 Gone responses.

The gzip filter in nginx only compresses 200, 403, and 404 responses today. A companion change in nginx/nginx adds 410 to that set (see nginx/nginx#1452).

This PR extends gzip.t with:

• a /gone location that returns 410 with a 64-byte text/plain body
• three assertions:
  • 410 gone — response status is 410 Gone
  • gzip 410 — response includes Content-Encoding: gzip
  • gzip 410 content — gzipped body decodes to the expected payload
