tests: explicitly specify 1k block sizes when creating test file systems

On the Hurd, mke2fs will force the use of 4k block sizes by default
because the Hurd's implemntation of ext2 doesn't support any other
block sizes.  This causes spurious test failures.  Since these test
are testing e2fsprogs functionality, force the use of 1k block sizes
so the test output matches the expected output.
