ci: exercise unsafe OpenSSL backend

In the preceding commit we have fixed a segfault when using an unsafe
SHA1 backend that is different from the safe one. This segfault only
went by unnoticed because we never set up an unsafe backend in our CI
systems. Fix this ommission by setting `OPENSSL_SHA1_UNSAFE` in our
TEST-vars job.
