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.
