wu-ftpd 2.4.2-beta-13 default UMASK hole

The default umask for wu-ftpd 2.4.2-beta-13 is 002.
Since most users on most sites are in the same group, all files created by
users PUTting files would be group writeable by anyone.  Not a good thing.

The offending code is in "ftpd.c" line 259:
#if !defined(CMASK) || CMASK == 0
#undef CMASK
#define CMASK 002
#endif

Changing CMASK 002 to CMASK 022 will fix this.
