sysutils/syslog-ng: Update to 3.38.1

Patch was created and tested by our upstream representative
Peter Czanik.

Syslog-ng developers develop for and test on Linux. The Syslog-ng has
been broken since 4.X. Peter Czanik, a Balabit employee, has been
maintaining a separate syslog-ng repo for FreeBSD until his patches
have been accepted by their development team. He will be using
the repo pointed to by the port until the FreeBSD issues are resolved.

Peter's extra effort is appreciated by the FreeBSD community.
