sntrup: Avoid linking issues in external_override tests

Browse Source 
This linking worked only in CI and local builds, but not during
the build in RPM as it fails on missing symbols that were defined
only in the main library. This is solved as with the other digest
dependencies in external crypto by removing the intermediate
function. We are already linking the md_*.o objects.

The error was like this

sh: symbol lookup error: /path/libssh/libssh-0.12.0-build/libssh-0.12.0/redhat-linux-build/lib/libsntrup761_override.so: undefined symbol: crypto_hash_sha512
