safety tile/dialog: Use GS_APP_QUIRK_DISTRO_SAFE

It's similar as GS_APP_QUIRK_PROVENANCE, but not the same, because
the provenance quirk changes how the repos dialog works.

The GS_APP_QUIRK_PROVENANCE can be used to show the apps as being
reviewed by the distro maintainers, rather than as being provided
by a third-party repository.
