Fix compilation error in primers/fileIO.chpl after r21066
Fix compilation error in primers/fileIO.chpl after r21066

Simple fix. The problem had to do with ENOERR being an
integer and now syserr is an enhanced error code (with a message),
where syserr used to be just an error code.

Not sure why I didn't see this in pre-commit testing. Mea culpa.
