    scannerparser.y: Really remove temp .h file on Windows
    
    In gi_source_scanner_parse_macros(), a temporary .h file is generated
    during the process of parsing the macros, and they aren't being deleted
    on Windows.  In turns out that the g_unlink() call in that function failed
    because Windows does not allow one to unlink/delete files while they are
    open, and that the g_unlink() call is done way early (for some reason).
    
    Fix this by calling fclose() on the fmacros FILE* *after* we are done
    with fmacros, and then finally call g_unlink() on the temp .h file.
