checksum tools stop on first failure (differs from GNU)

[chenxiaolong]

With uutils' checksum tools (like sha256sum), the program exits immediately when encountering the first error. This affects both the checksum generation (no args) and validation (-c) modes. This differs from GNU's implementations, which try to process every file before exiting.

For example:

echo 1 > file_1
echo 2 > file_2
sha256sum file_1 file_2 > checksums
rm file_1

echo "GNU output:"
sha256sum -c checksums
echo

echo "uutils output:"
coreutils sha256sum -c checksums
echo

returns:

GNU output:
sha256sum: file_1: No such file or directory
file_1: FAILED open or read
file_2: OK
sha256sum: WARNING: 1 listed file could not be read

uutils output:
sha256sum: failed to open file: No such file or directory

@sylvestre this issue should be closed?
