t/eu_command.t - sleep longer to make cygwin happy

We do a sleep 2 and then expect to see a 2 second difference
in the "newer file created" test, but sleep 2 does not necessarily
achieve a 2 second file differences. Upping the sleep call to 3
seconds should ensure we see at least 2 seconds difference on
operating systems like cygwin.
