Scan for 'stunnel4' before 'stunnel' since debian have them setup this way

and it should break most other systems. The "funny" part is that debian
actually have a 'stunnel' setup to simulate stunnel v3 but it breaks our own
stunnel-version-detect-and-adjust-to-it system.

Added initial support for optionally running servers with fork support.
