Re-submission of Leap 42.3 update kernel;
now fixed the missing module signature bug (bsc#1115587)

- rpm/kernel-binary.spec.in: Add missing export BRP_SIGN_FILES (bsc#1115587)
The export line was accidentally dropped at merging scripts branch, which
resulted in the invalid module signature.
- commit 9de753f

- rpm/kernel-source.spec.in: Add release-projects to the source
