Patch for findutils 4.1 on Tru64 Unix 5.1

[Petter Reinholdtsen]

Here is a patch to get findutils compiling on Tru64 Unix version 5.1.
The <fnmatch.h> header file is missing definitions for FNM_FILE_NAME,
FNM_CASEFOLD and FNM_LEADING_DIR.

I'm not sure if this is the correct fix, but at least now it compiles.
