[gtk-vnc] Initialize gcrypt before any auth method

[Daniel P. Berrange <dberrange src gnome org>]

commit e95446cb23cd17d7cbbb8eb9e20211b14a41a9cf
Author: Daniel P. Berrangé <berrange redhat com>

    Initialize gcrypt before any auth method
    
    The gcrypt APIs are now used in multiple auth methods, so we should
    initialize them early, rather than only in the TLS codepath.
