cksum: fix --check with non tagged format checksums

Browse Source 
* src/digest.c: Always set the digest_length, so that
we check the correct number of hex digits when parsing
non tagged format checksums.
* tests/misc/cksum-a.sh: Add a test case.  Also fix
up this test which was ineffective due to fail=1
being set in a subshell and ignored.
