If canon'ing principals, write ccache with updated default principal
* When calling krb5_get_init_creds_keytab() with krb5_get_init_creds_opt_set_canonicalize() the credential principal can get updated. * Create the cache file with the correct default credential. * LDAP GSSAPI SASL would fail due to the mismatched credentials before this patch. https://bugzilla.redhat.com/show_bug.cgi?id=811518
