Fix recently introduced Win32 child spawning code in mod_rewrite.c which was

broken because of invalid ap_pstrcat() -> strcat() transformation.  I'm a
little bit confused: Seems like no one has actually compiled Apache with all
modules under Win32 just before Jim rolled the 1.3.0 tarball. Because else
someone had received a compile error. Hmmm... I knew why I hates to put code
into mod_rewrite I couldn't test myself... :-(
