Fix compilation on eclipse-titan 6.5.1

Newer eclipse-titan makefilegen already sets CPPFLAGS like this:

CPPFLAGS = -D$(PLATFORM) -I$(TTCN3_DIR)/include$(TTCN3_SUBDIR)

where TTCN3_SUBDIR expands to '/titan' and TTCN3_DIR to '/usr'

If we add /titan after include we end up with
-I/usr/include/titan/titan/ which will cause the compile to fail due to
a missing TTCN3.hh include.

Check the titan version so we retain backwards compatibility.
