File 0010-OCI-correctly-handle-locally-present-icons.patch of Package flatpak.25785

Subject: [PATCH] OCI: correctly handle locally present icons

If the download URL for an icon was already cached locally, the HTTP
code returned FLATPAK_OCI_ERROR_NOT_CHANGED - this was treated as a real
error, and after downloading missing icons, all present icons were
deleted!

See https://bugzilla.redhat.com/show_bug.cgi?id=1683375

Closes: #3048
