rpm: use same options for creating symlinks as in the deb builds

Use the same options for creating the symlinks as for the deb packages, and
add the `-n` and `-f` options;

    -n, --no-dereference        treat LINK_NAME as a normal file if
                                it is a symbolic link to a directory
    -f, --force                 remove existing destination files
