    cmake.bbclass: call cmake with a relative path

    CMake wants a relative path for CMAKE_INSTALL_*DIR, an absolute path
    breaks cross-compilation. This fact is documented in the following
    ticket: https://cmake.org/Bug/view.php?id=14367

    $sysconfdir and $localstatedir are not relative to $prefix, so they are
    still set as absolute paths. With his change ${PROJECT}Targets.cmake
    that are generated by cmakes "export" function will contain relative
    paths instead of absolute ones.

the hacky sysroot replacements are no more necessary.
