paths: Support binary packages
Currently VSPERF supports OVS, DPDK and QEMU built from the source code only. In some cases it is required to support installation of these tools from binary packages available for given linux distribution. Thus VSPERF configuration and code was modified to suport both source and binary versions of tools. This can be configured perf tool, so various combinations of source and binary version are supported. Together with new configuration also a handling of kernel modules was modified to automatically detect and load module dependencies.
