quickpkg: enable include-unmodified-config by default

If the user has not modified an installed config file, there should be
no risk of exposing secret information by including the file.

This makes quickpkg behave more reasonably with
FEATURES="config-protect-if-modified", which has been enabled by default
since 304dfb0.
