build: reduce size of multi-call binary by reusing cksum logic
Map md5sum and sha{1,224,256,385,512} to use cksum logic,
which selects appropriate behavior at runtime, rather than
separate binaries for each closely related utility.

* build-aux/gen-single-binary.sh: Map sha*sum to use cksum.c
* src/cksum.c: Adjust to behave more like sha*sum,
when the algorithm to something other than "crc".
* src/cksum.h: Expose the cksum_algorithm global and enum.
* src/coreutils-md5sum.c: Set cksum_algorithm and call cksum logic.
* src/coreutils-sha1sum.c: Likewise.
* src/coreutils-sha224sum.c Likewise.
* src/coreutils-sha256sum.c Likewise.
* src/coreutils-sha384sum.c Likewise.
* src/coreutils-sha512sum.c Likewise.
* NEWS: Mention the improvement.
