Subject: [PATCH] Add build options for Sparkle updater

Two new build options are added:

`MAC_SPARKLE_PUB_KEY`: the public key used to verify the signatures of the appcast
`MAC_SPARKLE_APPCAST_URL`: the URL where the `appcast.xml` is located

If the updater should be disabled on macOS, set either of these to an empty string.
