Subject: linux: Add MMAP_ABOVE4G from Linux 6.6 to sys/mman.h

x86 added the flag (29f890d1050fc099f) for CET enabled.

Also update tst-mman-consts.py test.

Conflicts:
	sysdeps/unix/sysv/linux/tst-mman-consts.py
	  (removed patch to keep alerting about kernel differences)
	sysdeps/unix/sysv/linux/x86/bits/mman.h
	  (adapted to missing __USE_MISC conditional upstream)
