[gegl] docs: Put inheritance.png in builddir

    docs: Put inheritance.png in builddir
    
    Cause make distcheck to pass by outputting inheritance.png in the
    builddir rather than source dir. The documentation is still messed up
    when having srcdir != builddir, but at least we pass make distcheck.
