websocketpp: add various upstream accepted and proposed patches to fix various issues, including:

- build failure with boost 1.71
- bad installation of header files correct version on some OSes.
- fix version minor number
- fix Scons script not being Python3 ready
- build examples and tests only if ptest is enabled in DISTRO_FEATURES
- do not depend on websocketpp from -dev package, because this is an header only dev package for now
