[Buildroot] [PATCH] swupdate: install web application version 2

[Stefan Becker <chemobejk@gmail.com>]

The old web application under www/ and mongoose API v1 no longer work
after upgrading to 2018.03. Install web application version 2 from
examples/www/v2/ to /var/www/swupdate/ instead.

This fix does not address the fact that you can't rebuild the new web
application under buildroot. That would require host Node.js & npm to
run the application build. I.e. for now users have to live with the
example application or apply patches directly to the built version of
the appication.
