xfstests: Accesstime issues (xfstest generic 003, 192)

xfstests 003 fails with: +ERROR: access time has not been updated after accessing file1 first time +ERROR: access time has not been updated after accessing file2 +ERROR: access time has not been updated after accessing file3 second time +ERROR: access time has not been updated after accessing file3 third time

xfstests 192 fails with: -delta1 is in range +delta1 has value of 0 +delta1 is NOT in range 5 .. 7

both cases seem to be simple a) access file b) check access time c) sleep d) access file again e) check access time

and the access time hasn't moved. It doesn't seem to matter if we change the underlying mount atime flags.
