Log Message:
games/caesar: fix error handling for I/O

The '!= 0' is needed for an upcoming fix to lint's strict bool mode.

The additional text in the error messages is necessary because errx only
outputs the given string, with no details from errno.  Since ferror does
not set errno, no such details are available, so just output a generic
message, which is still better than just "caesar: <stdout>".
