[meta-oe][PATCH] hiredis: add cmake config file for pkgconfig

[Peter Bergin]

In order to be able to use pkgconfig and find_package in
cmake the file HiredisConfig.cmake need to be present
in sysroot. This commit adds a patch from Ubuntu/Debian
that fixes this. As build system for version 0.14 of Hiredis
is Makefile based this is not possible to upstream. In
later Hiredis the build system is CMake based and this is
fixed.
