python3-pybind11: Use cmake to build and add -native version

* Switch to git repo to pick up cmake files for recipes to use
 * Use cmake to build innstead of pypi so cmake files are included in sysroot
 * Disable tests to prevent configure failure (I tried adding pytest asa DEPEND)
 * Patch out cmake that strips output to prevent QA failures
 * Do not check pointer length for installed python when cross compiling.
 * With this I can build gnuradio using pybind11.
