[roll] Roll fuchsia [components] Namespaces support EXECUTABLE right

With this change, the namespace directories that are built by component
manager have the EXECUTABLE right.

This change does not effect on service nodes (protocols). Directories
that are added to the namespace (from cml `directory` capabilities for
example) are also not affected, except that they now support EXECUTABLE.
