amend to f3dbc9dda10e52610e3de26f538b5581fd905505: change main thread-name back to `fail2ban-server`;

implements new command line option `--pname` to specify it by start of server (default `fail2ban-server`);
closes gh-2623 (revert change of main thread-name, because it can affect process-name too, so `pgrep` & co. may be confused)
