Deal with configuration values that change state in common/ark/fedora by moving back to pending-

Often a configuration value we've previously set changes state because a new dependency is introduced or it changes from, say, tristate to bool. At the moment the configuration automation doesn't account for this so when it goes to build the SRPM everything explodes.

Instead, it should move the configuration options in question back from ark/, common/ or fedora/ into the relevant pending directory with the new default so they can be re-reviewed.
