[evolution-data-server] Fix build issue when not using Kerberos.

[Matthew Barnes <mbarnes src gnome org>]

commit f6a1d8754a83fe147ef89cc29dcff4cf8c19ce0c
Author: Matthew Barnes <mbarnes redhat com>

    Fix build issue when not using Kerberos.
    
    Apparently when building without Kerberos support the entire contents of
    camel-sasl-gssapi.c is omitted, which breaks generating API docs because
    camel-scan.c expects a camel_sasl_gssapi_get_type() regardless.
    
    With this commit, when building with Kerberos support, CamelSaslGssapi
    is still a registered CamelSasl subclass but it does absolutely nothing
    and is never used by Camel's SASL support.
