[sheepdog] [PATCH v3 02/13] tests: use mkfs.ext4 only for _make_device

[Liu Yuan]

This is a preparation patch for 'remove -s option'. After '-s' is removed,
since every file system has its own metadata allocation mechanism, so we can't
use different file system to get the same size after formatting.
