luci-proto-{wireguard,yggdrasil}: remove unnecessary PROVIDES

Remove the unnecessary PROVIDES statements from two protocols.

Wireguard was recently changed erroneously: the old compatibility
reference to luci-app-wireguard was replaced by self-reference.
But as the app and proto were combined already in 2022, the old
compatibility define should be unnecessary by now, so just remove it.

Yggdrasil has had a similar unnecessary setting (package
PROVIDES itself), so remove that at the same time.
