services: fail2ban: Start server in the foreground.

Previously, we were passing '-b', thereby starting the server in the
background.  Consequently the 'start' method could complete before the
server was ready to accept connections on its socket, leading to
non-deterministic test failures.

Reported by Mathieu Othacehe <othacehe@gnu.org>.

* gnu/services/security.scm (fail2ban-shepherd-service): Change
FAIL2BAN-ACTION to invoke 'fail2ban-client'.
Change 'start' method to use 'make-forkexec-constructor'; start the
server in the foreground with '-f' and pass '-x' to force execution of
the server, as done upstream in 'fail2ban.service.in'.
