Fix an issue with refresh with external frame flags.

For the case where the user supplies the frame_flags
via the EFLAG_NO_UPD_#:
LAST should be used instead of LAST3 in get_refresh_frame_flags.

Added an example (case 4) for 2 temporal layers in svc_encoder_rtc
to verfiy this.

In general for RTC appplication the new svc.external_ref_frame_config
should be used for setting the references and updates, so this is an
non-issue for that case. This change only affects the case where user
uses the old EFLAG_NO_UPD_# flags.
