mman.h still has MAP_FAILED as caddr_t

[Yitzchak Scott-Thoennes]

The prototypes for mmap, etc. were recently changed from using caddr_t
to void *, as called for by SUSV3, but MAP_FAILED wasn't changed.
SUSV3 doesn't specifically say anything about how MAP_FAILED should
be defined, but other platforms I've seen have a (void *) cast.
