We need to make sure that file writes,file creation, etc. are properly performed and do not corrupt the filesystem. To help with this, introduce the assert_fs_integrity() function that executes the appropriate fsck tool. It should be called at the end of any test that modify the content/organization of the filesystem. Currently only supports FATs and EXT4.
