Fix for mod_rewrite's dbd/fastdbd initialization

Without the attached patch, httpd randomly crashes at startup, when one
attempts to use the new dbd-style RewriteMap.

valgrind points at the use of uninitialized memory in mod_rewrite.c:3068 --
indeed, when the map is of type dbd (or fastdbd), the newmap->checkfile remains
uninitialized. The proposed patch fixes the problem by explicitly setting the
field to NULL (there are no files to check in this case).
