[fix] scripts: elimination of limitations on dedicated distributions

The restriction of shell scripts to certain distributions is only required for
certain actions such as the installation of a SearXNG instance. The maintenance
scripts and build processes were previously also restricted to these specific
distributions.  With this patch, the build processes (such as the build of
online documentation) can now also be executed on all Linux distributions.
