net-libs/libvncserver: always enable gcrypt-based crypto backend

There are a few reasons for that:
- internal crypto backend doesn't support all authentication methods and
  the use of external crypto backend was already forced via REQUIRED_USE
- openssl-based crypto backend is completely broken with openssl-3.0
- build system does not allow to disable openssl-based crypto backend when
  openssl-based TLS backend is enabled without also enabling gcrypt-based
  crypto backend
- all major distros are building with gcrypt-based crypto backend, so it
  is the most tested configuration.
