[PATCH] md5sum, sha*sum: improve help for --check related options

[Pádraig Brady]

* src/md5sum.c (usage): s/three/four/ in the message pertaining
to the --check related options.  Also clarify that --strict
is just significant for the formatting of the checksum lines.
Also since we're changing both strings, move the --strict description
in with the description of the other options and order alphabetically.
* THANKS.in: Added reporter: Daniel Mach
