For PACKAGECONFIG settings in recipes, we care about the end value, we don't
really care how it is constructed. bbappends to recipes can add things to
the default PACKAGECONFIG settings, for example being dependent on a DISTRO_FEATURE
or other variable. If the computed value doesn't change, the task hashes can remain
constant, allowing for better sstate reuse.

To do this, set a vardepvalue of the variable value itself, ignoring how
the actual value is calculated.
