[Buildroot] [PATCH 1/1] msgpack: new option install libs

From: bradford barr <bradford at density.io>

New option to install libs. MessagePack is implemented both as a C++ header and
a C runtime library. If all applications linking to msgpack use the C++ header
library there's no need to install the C library. This option allows a user to
prevent installing unused libraries.
