obs-outputs: Fix TLS_client init for mbedTLS 3.1.0+

When trying to update to mbedTLS 3.2.1, I ran into failures with RTMPS
output. After consulting an mbedTLS implementation example, I determined
that we were not setting up the SSL/TLS context config in the correct
order, causing the connection to fail. Performing the setup in the
recommended order fixes that.
