Fixed timestamp_offset for RtpSenderEgress during initialization and SetRtpState call

The constructor and SetRtpState calls for ModuleRtpRtcpImpl2 class fail to propagate the RTP timestamp offset of RtpSender class to RtpSenderEgress class. This results in wrong RTP timestamps being propagated in LossNotification messages.
