[PATCH 5/7] signatures: unify WKS_* variable exclusions with OE

[Felix Moessbauer <felix.moessbauer@siemens.com>]

This patch unifies the variables that are excluded from the signature
computation with its counterpart in OE.
The excluded variables contain absolute paths that point into the build
host. By excluding, we make the builddir relocatable.

This improves sstate cacheability.
