PktSrc/RunState: Scale on first_wallclock and move pseudo realtime logic to RunState

Browse source 
check_pseudo_time() used zeek_start_time which skews things sufficiently
around being in the past when ZAM compilation takes multiple seconds. Switch
to using first_wallclock instead.

Further, move setting of first_timestamp and first_wallclock from PktSrc
into RunState's dispatch_packet(), so it's more centralized now.

The only pseudo_realtime piece left in PktSrc() is in GetNextTimeout() to
determine how long the PktSrc is idle until the next packet is ready.
