Use truncate instead of fallocate in ziltest.sh

For the purposes of creating sparse files the truncate command is preferable to fallocate because generic sparse files are more widely supported by older platforms. Specifically Debian Wheezy which is based on a 2.6.32 kernel used ext3 by default which at the time did not support it. Signed-off-by: Brian Behlendorf <[email protected]>
