uwsgi 2.0.8

Version bump, new OpenSSL dependency to fix tapping the system, and a patch I improvised from gearman for Yosemite to fix compile issues.

Closes #33488.
No, I didn't know whether to bother or not. It works and fixes compile issues, but it is a hacky patch to implement and I didn't know if upstream wanted to do their own thing here. I guess I could submit just the bug report.
