be64enc, be16dec, and be32dec are declared on FreeBSD 13.0, in
/usr/include/sys/endian.h so we should not declare them.
Fixes the following error during feeds update:
staging_dir/host/bin/mkhash: No such file or directory
gcc scripts/mkhash.c
scripts/mkhash.c:111:1: error: redefinition of 'be64enc'

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

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.

The -n option prints the filename of hashed files next to the calculated
checksum. Reflect that in the usage message.
