burgerspace: update to 1.9.4

2021-06-18: Version 1.9.4 released

    New option --no-active-event allows the user to avoid the
    automatic pausing that happens when the window loses the focus
    or is iconified.

    The sound files are now installed under /usr/share/burgerspace/sounds
    instead of /usr/share/sounds/burgerspace (assuming /usr as the
    installation prefix).

    The burgerspace-server manual page is now only installed if
    the network version is built.

    The COPYING license file is not installed anymore.

    Resolved g++ 9.3.0 compilation warnings.
