scapy: Load default SCAPY protocols
After the fix of SCAPY library import, it was not possible to use some of the network protocols by T-Rex. T-Rex 2.38 uses by default SCAPY 2.3.1 for python3, but it overrides the default set of network protocols loaded by layers/all.py. VSPERF makefile was modified to restore original version of all.py from SCAPY 2.3.1 git repository. Also examples of scapy usage were updated to generate correct traffic with modified scapy version.
