debuginfod: let nginx compress octet-stream responses

Using the fastest gzip compression level to avoid burning too much CPU.

Draft MR until we gather some CPU usage metrics with this deployed.

Edit: There's the odd spike in the CPU usage graph but seems fine, especially when taking !575 (closed) into consideration.
