Allow running reproducibility checks on direct uploads

[bbhtt]

Currently, all direct uploads are excluded for one reason or the other, but mainly because they don't send the whole sources that was used to build in the .Sources extension.

	UNSUPPORTED_FLATPAK_IDS = (
	"org.mozilla.firefox",
	"org.mozilla.Thunderbird",
	"net.pcsx2.PCSX2",
	"org.duckstation.DuckStation",
	"net.wz2100.wz2100",
	"com.obsproject.Studio",
	)

Now that I enabled uploading .Sources extension for direct uploads, we should ensure they send us all the sources.
