[PATCH:imake 2/2] Ensure inFile is always closed on error in cppit()

[Alan Coopersmith]

Another instance of the can-return-in-rare-cases nature of LogFatal()
raising red flags in static analysis.

Resolves warning from Parfait 1.0.1:
Error: File Leak
   File Leak: Leaked File inFile
        at line 1719 of imake.c in function 'cppit'.
          inFile initialized at line 1699 with fopen
          inFile leaks when inFile != NULL at line 1700
              and fprintf(inFile, "%s\n", "/* imake - temporary file */") < 0 at line 1702.
