Fix CI

Use GitLab Registry for CI purposes.  Disable EdDSA support for Debian
sid since the OpenSSL version shipped with it has broken Ed448 support.
Use /dev/urandom as the random device in the "ecdsa" system test to
prevent newer OpenSSL versions from running out of entropy when
verifying ECDSA signatures.
