Subject: [PATCH] Remove file mode hardcode from file_write

This function was always including the binary flag ("b") during
fopen(2), which seems to be inappropriate for the --output.roa and
--output.bgpsec files.

Well, the Unixes don't do anything with this flag, so this is more of a
semantic fine-tune than a bugfix.
