[OE-core] [PATCH] base.bbclass: Don't warn about "invalid" PACKAGECONFIGs by default

[Olof Johansson]

The recently added warnings for recipes that try to use undefined
packageconfigs isn't compatible with the PACKAGECONFIG approach of
exporting a common set of configs and letting the recipe look only at
the configs they care about.

This change introduces a STRICT_PACKAGECONFIG variable that one can
enable to get the warnings.
