dtdocbook/tcl/tcl.h: Add compatibility defines for old Tcl

Browse source 
dtdocbook/instant has been modified to use a more modern Tcl (8.6),
which means certain functions are not present when we are using the
dtdocbook/tcl (7.5) version of tcl instead of a modern system version.

So, create some defines that should work around this problem.
