build: add support for building with meson

Follow the OpenBMC herd and support a more modern, more comprehensible,
more performant build framework.

To build using meson:
   meson build
   ninja -C build
   ninja -C build install

Added -Dtests to match de-facto OpenBMC meson usage conventions.

Dropped support for --enable-oe-sdk rpath munging.  This was a
workaround for broken oe sdks that don't figure out the correct rpath
when running make check or ninja test.

Ran existing unit tests (which passed) using ninja test.
