www/ungoogled-chromium: configurable cdm pledges

Hi,

I'd like to propose changing ungoogled-chromium port to read pledge
configuration for CDN sandbox from a config file instead of having it
hardcoded to what openvw needs.

That would make it easier for any alternative implementations that may
require a different set of pledges.

Here is a diff with the proposed change, default pledge remains the
same:
