base/genht.c: add a preprocessor define to allow fopen calling

The commit in upstream:
http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=773c69e46e70bdd5482676437dafd2ca83397643

Replace all fopen calls with gp_fopen and add a preprocessor define so
that any unintential calls directly to fopen will cause an error.

Only exceptions are those in the platform specific code, and mkromfs.c.
This patch add a preprocessor define to allow fopen calling in base/genht.c.
