test suite: account for lacking precision of os.utime() 

os.utime() uses the utimes(2) system call to set file timestamps.  utimes(2)
has a microsecond resolution, but stat(2) may return timestamps with
nanosecond resolution.  So, the check that we have properly reset the mbox
file timestamp must allow a minor deviation.
