test: fs: fs-test: Move the tests to use sha256sum
Move the use of md5s for recording filesystem file integrity checks to sha256 hashes as they're preferred due to being less likely to produce clashing hashes. In the process generalise some of the wording to use the more generic hash term. Signed-off-by: Peter Robinson <pbrobinson@gmail.com>
