[PATCH 2/7] backport: resurrect integrations

Couple fixes to fix the kernel build when using a built in
backports ("integration mode"):

- newer kernel kconfig doesn't seem to like evaluating
  variables with just '$'. Use '$()'.
- define BACKPORT_DIR in the integration Kconfig so we
  don't have to supply it in an environment variable
  (where it can probably only ever be "backports/"
  anyway).
