tests: Remove p11-kit remoting from pkcs11 tests

The p11-kit remoting was initially introduced because softhsm
was crashing during cleanup with OpenSSL 3.0. This was resolved
since then and this code introduces a lot of complexity and
possible bugs, such as when using the mechanisms from PKCS#11 3.0
that are unknown to the p11-kit remoting tool. It decides to remove
them from the list as demonstrated here:

https://github.com/p11-glue/p11-kit/issues/668

This resulted in pkcs11-provider not registering EDDSA siganture
methods to the OpenSSL and failing when asked to provide a singature
by the Ed25519 key from the PKCS#11 token.
