Increase maximum video size accepted by Enketo Express

This is controlled by the HTTP header X-OpenRosa-Accept-Content-Length sent by KC. That's not yet configurable by environment variable, but I've opened an issue for that: kobotoolbox/kobocat#435.

Let's use 100 megabytes for X-OpenRosa-Accept-Content-Length and increase the NGINX limit to 105 megabytes (if you think that's enough headroom). Overall, the HTTP request needs space to include:

• Binary attachment up to 100 megabytes
• XML of the submission (text responses only; not large)
• Whatever overhead multipart form data incurs

@noliveleger Is this still pending re accepted attachment sizes by EE?

It seems it is.
