Fix the SourceSet.projectDefault() extension adding sources to resources

The `include` calls were effectively made on the `resources`
`SourceDirectorySet`, which meant including '**' from 'src' as well.

Since the 'SourceDirectorySet' API is quite limited and does not support
specifying includes/excludes separately, configure the
`ProcessResources` task instead.
