[PATCH v1] cmd: md5sum: use hash_command

From: Igor Opaniuk igor.opaniuk@gmail.com
Drop old implementation and use hash_command() instead, as how it's currently done for crc32 and sha1sum cmds.
Test: => md5sum 0x60000000 0x200 md5 for 60000000 ... 600001ff ==> e6bbbe95f5b41996f4a9b9af7bbd4050

Are there currently any objections that can prevent these cosmetic cleanup from being applied? If there are any - just let me know, thanks
