Add a statx attribute bit STATX_ATTR_VERITY which will be set if the
file has fs-verity enabled. This is the statx() equivalent of
FS_VERITY_FL which is returned by FS_IOC_GETFLAGS.
This is useful because it allows applications to check whether a file is
a verity file without opening it. Opening a verity file can be
expensive because the fsverity_info is set up on open, which involves
parsing metadata and optionally verifying a cryptographic signature.
This is analogous to how various other bits are exposed through both
FS_IOC_GETFLAGS and statx(), e.g. the encrypt bit.
