Added launchtime flag to talker

Sometime ago spin wait was made separate from fixed_timestamp,
this caused regression in builds using IGB_LAUNCHTIME_ENABLED=1.

This adds launchtime flag to talker which will be set automatically
if IGB/ATL_LAUNCHTIME_ENABLED is used.

Otherwise we would need to use spin_wait flag to make launchtime
work which would be counter-intuitive.

Both spin_wait and launchtime mode work on WALLCLOCK, but launchtime
doesn't need any waiting because it will be done in ethernet driver.

So, we will have 3 modes for packet scheduling:
    sleep
    spin_wait
    launchtime
