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.
