Don't check the link type from stubs libs.

getLinkType also tells whether the module in question is a stubs lib or
not. If it is a stubs lib, link type from it isn't checked beause
dependency from the stubs lib doesn't matter; the stubs lib is
build-time only artifact.

In addition, core-lambda-stubs is added to the list of stubs libs.
