software/seleniumserver: rename seleniumrunner to seleniumserver

seleniumrunner software recently became a full selenium server, which is
different from the original software, that was only intended as being a
minimal software to make firefox available for erp5testnode.

This caused several problems in erp5testnode, because erp5testnode needs
to be always able to build seleniumrunner from master branch (which is
probably wrong in the first place). With this software having lots of
components, the risk of build problems increased.

Also, it's something else, so let's make it another software.
