In generic/135, benign warning message output from _scratch_mkfs on stderr can cause a golden output mismatch, as can occur when testing an ext4 bigalloc file system. It's the only generic test that does not also redirect stderr when directing _scratch_mkfs' stdout to /dev/null. Since error output from _scratch_mkfs doesn't seem important to the overall intent of the test, there should be no harm in making its stderr handling consistent.
