This is an initial commit to improve anonimity in Nayuos R69+. It adds
the most common user agent string (Chrome R68 on Windows 10) to the
chromium process at startup.
This is also the first addition of a patching message to modify the
ChromiumOS code. It does not modify the chromium browser code, which
will be necessary for successive anonimity feature additions.

This patch compiles, but it has not been tested if the user agent is
actually modified when run on a board
