fix: services.<name>.service.build.context

One could declare it, but it was unceremoniously ignored.
A "localhost/" image was created with pretty much nothing in it
 and it couldn't be launched.

The cause was services.<name>.service.image being always set
 and subsequently thugs services.<name>.image.nixBuild being truthy.
That would build an image and write the services.<name>.image field
 in the docker-compose.json. It leads to the build.context being
ignored and the service failing.

This was solved by only writing services.<name>.service.image when
 services.<name>.service.build.context is not set.
services.<name>.image.nixBuild is additionally set to false when
the context is set.
