pktgen: Add behaviour flags macro to generate flags/names

Browse Source 
PKT_FALGS macro will be used to add package behavior names definitions
to simplify the code that prints/reads pkg flags.
Sorted the array in order of printing the flags in pktgen_if_show()
Note: Renamed IPSEC_ON => IPSEC for simplicity.

No visible behavior change expected.
