Peter Oberparleiter a97a8f1cba libutil: fix util_file_write_* return code ...

By default, files opened via fopen are block-buffered. As a result,
I/O errors that occur during file write operations via util_file_write_*
are silently ignored because fputs() only buffers data while actual I/O
occurs during the flush operation that is part of the final fclose()
library call.

Fix this by indicating errors that occur during fclose() via the
util_file_write_* function return code.
