bits/mman.h: consolidate header file
Sync with GNU C library and consolidate duplicate non
architecture specific defines.
MAP_UNINITIALIZED is only defined to 0x4000000 and used by
the Linux kernel when CONFIG_MMAP_ALLOW_UNINITIALIZED is enabled.
CONFIG_MMAP_ALLOW_UNINITIALIZED is only available for nommu.
See Documentation/nommu-mmap.txt.
