selftest: Fix timestamps on FreeBSD 11

FreeBSD's date does not print the %, and \? does not catch that

Tested this manually:

$ echo 'time: 2016-11-23 12:52:19.123456Z'| sed 's/\..*NZ$/.000000Z/'
time: 2016-11-23 12:52:19.123456Z
$ echo 'time: 2016-11-23 12:52:19.%6NZ'| sed 's/\..*NZ$/.000000Z/'
time: 2016-11-23 12:52:19.000000Z
$ echo 'time: 2016-11-23 12:52:19.6NZ'| sed 's/\..*NZ$/.000000Z/'
time: 2016-11-23 12:52:19.000000Z
$ echo 'time: 2016-11-23 12:52:19.NZ'| sed 's/\..*NZ$/.000000Z/'
time: 2016-11-23 12:52:19.000000Z
$
