[Buildroot] [PATCH 1/1] support/cmake: Explicitly set CMAKE_SYSTEM

[Frank Vanbever]

Some packages test for CMAKE_SYSTEM explicitly.[1]

CMAKE_SYSTEM is comprised of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION.
It defaults to CMAKE_SYSTEM_NAME if CMAKE_SYSTEM_VERSION is not set.[2]

At the point CMAKE_SYSTEM_NAME is set to "Linux" CMAKE_SYSTEM is already
constructed. Setting it explicitly ensures that it is the correct value.
