Update comment:

version assembly to be able to refer to them below and make sure chrome.exe can
find them at runtime), except the ones that are already staged (i.e.

When would |runtime_deps| ever not be specified? Would rather not keep a code
path that isn't exercised.

Do we currently want to continue supporting gyp with mini_installer?
