test: relax the FS test a slight bit to be more reliable

Some filesystems track atime always.  This relaxes the test to accept either a
filesystem which does not accurately track atime or does track the atime
accurately.  This allows the test to pass on filesystems mounted with
`strictatime` on Linux or on macOS.
