[meta-oe][PATCH] nlohmann-json: Add symlink to json.hpp and update to 3.3.0

[James Feist <james.feist@linux.intel.com>]

nlohmann-json has examples in their repo that refer to
the header as json.hpp directly, as such many packages
that require nlohmann-json expect json.hpp and not
nlohmann/json.hpp as the cmake file installs. Create symlink
so that access is available by either option. Also update
to release 3.3.0.
