Make created root certificate static

[JonSnowWhite]

Problem

Currently resources/static/root contains a private-key.pem that does not correspond to the values used in the X509Certificateconfig. I.e., the CA certificate is different than the one used by X509-Anvil.

X509-Testsuite/resource/out contains certificates produced by X509-Anvil, but the root certificate changes between runs.

This way, we cannot provide a CA cert to a tested server that will lead to the server accepting our certificate.

Task

Make the root certificate produced by X509-Attacker/X509-Anvil static and provide it such that a server can use it as the CAfile
