[Buildroot] [PATCH] pkg-cmake.mk: set CMAKE_SYSROOT variable in toolchainfile.cmake

This change enforces the CMAKE_SYSROOT value set in the toolchainfile.cmake.
This fix overrides the CMake heuristics used to guess it, and turns off some
non-desirable behavior adding "-isystem ..." flags to the compiler command
line, misleading the compiler and making the build failed due to some
unfound standard headers.
