This patch adds the new STATX_MNT_ID, STATX_ATTR_MOUNT_ROOT and
STATX_ATTR_DAX macros from Linux 5.8 to glibc's bits/statx-generic.h.
(As with previous such changes, this only does anything if glibc is
being used with old kernel headers.)
A comment in the Linux kernel headers indicates that STATX_ALL is
deliberately not being changed.
Tested for x86_64.

Do we also need to update struct statx?

The intent was not to update it. The definitions are only active if
the installed kernel headers are too old. We probably should not
change the version conditional because that would make the member
types more unpredictable (the __u64 vs uint64_t issue).
