This patch updates the hppa bits/mman.h based on Linux 4.14.  Some
MADV_* macros are removed in Linux 4.14 as unused/unimplemented, so
this patch removes them from glibc, while adding two new macros added
in Linux 4.14.

Tested (compilation only) for hppa with build-many-glibcs.py.

	* sysdeps/unix/sysv/linux/hppa/bits/mman.h
	[__USE_MISC] (MADV_SPACEAVAIL): Remove macro.
	[__USE_MISC] (MADV_VPS_PURGE): Likewise.
	[__USE_MISC] (MADV_VPS_INHERIT): Likewise.
	[__USE_MISC] (MADV_HWPOISON): New macro.
	[__USE_MISC] (MADV_SOFT_OFFLINE): Likewise.
