Use %cmake_ macros to fix out-of-source builds
    
    The out-of-source builds are now enabled by default, see:
    https://fedoraproject.org/wiki/Changes/CMake_to_do_out-of-source_builds
    
    Use %cmake_build and %cmake_install macros and also remove redundant
    statements for winpr tools to fix the broken build.
