Goal

This change will fix a regression we noticed in our Rust bindings unit tests.

Why

I unknowingly caused a regression in a unit test when I added TLS13 ciphersuites to the default policy (#5560). The test was originally erroring without blinding, and my change made it error with blinding. Therefore the unit test timings increased quite a lot.

How

I just changed the server config to use the fixed TLS12 policy, instead of the default policy. I also added some time checks to assert that this test does not trigger blinding, as that was missing from the original test.

Callouts

Another notch for #5557

Testing

Handshake tests should now pass in one second instead of a varying between 10 and 30s.
Mainline test timing:
test result: ok. 8 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 28.54s
PR test timing:
test result: ok. 8 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 1.13s
