fcd3e13779 scripts: mkhash fail on hashing a folder
mkhash currently returns the hash of an empty input when trying to hash
a folder. This can be missleading in caseswhere e.g. an env variable is
undefined which should contain a filename. `mkhash ./path/to/$FILE`
would exit with code 0 and return a legit looking checksum.

A better behaviour would be to fail with exit code 1, which imitates the
behaviour of `md5sum` and `sha256sum`.

To avoid hashing of folders the `stat()` is checked.

Hashing empty inputs result in the following checksums:
md5: d41d8cd98f00b204e9800998ecf8427e
sha256: e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

fac98f1c54 scripts: mkhash fix return code handling
If hashing a file fails mkhash shouldn't just silently fail. Now check
after each call of `hash_file()` the return and exit early in case of
errors. The return value which was previously ignored and would always
return 0.

91a0dc5161 scripts: mkhash show -n option in usage
The -n option prints the filename of hashed files next to the calculated
checksum. Reflect that in the usage message.

dad48c6438 build: add a small standalone utility for calculating md5/sha256 hash
This will be used to simplify the build system code for checking hashes.
Instead of using various variants of md5sum / openssl, use one simple
utility for all of them
