The 'seq' command is not available by default on OpenBSD, so these
iotests are currently failing there. It could be installed as 'gseq'
from the coreutils package - but since it is using a different name
there and we are running the iotests with the "bash" shell anyway,
let's simply use the built-in double parentheses for the for-loops
instead.
