Fix 1988/litmaath/README.md + add alt code

There was no 'To build' or 'To run' section.

The alt code is that which the judges suggested to try and understand
the code a bit more. As it was fun output and it seems instructive I
decided to add it as an alt version.

Updated .gitignore.

+[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) added the
+[litmaath.alt.c](litmaath.alt.c) which we described in our remarks below. To

+```sh
+make alt

+Use `litmaath.alt` as you would `litmaath` above.
