[Buildroot] [PATCH 1/1] json-for-modern-cpp: use include.zip

[Yann E. MORIN <yann.morin.1998@free.fr>]

Adam, All,

> Currently, the json for modern c++ uses the release tarball for configuring
> and installation. However; this tarball is actually 114.5Mb of unit tests, and
> 500Kb of actual code, which is just a header file.
> 
> When the package was initially submitted to Buildroot, json for modern c++ only
> had the option of either just the header file, or the tarball. Since then,
> the project has been able to break apart the header file into several, more
> managable files and have included them in a "include.zip" file for each release.
> This tar file is only 134K, and includes no unit tests.
> 
> This patch does the following:
> - Change the package to a generic package.
> - Manually unzip and install the header files to staging.
> - Update the sha256 hash's for the new files.

So, the release file does not include the version in its name. That's
sad. Very sad... :-(

I think I'd prefer that we find another solution...
