Set the default gio.TlsDatabase used to verify TLS connections
Any subsequent call to g_tls_backend_get_default_database() will return
the database set in this call. Existing databases and connections are not
modified.
Setting a NULL default database will reset to using the system default
database as if g_tls_backend_set_default_database() had never been called.
