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)
