[PATCH] ox.el: Protect export from auto-formatting hooks

[David Lukes <dafydd.lukes@gmail.com>]

* ox.el, ox-odt.el: Use `write-region' instead of `write-file' or
`save-buffer' to protect generated export buffers from auto-formatting
hooks.

In particular, `tidy' is often configured as the auto-formatter for HTML
and XML, and it can corrupt the exports.
