wgengine/wglog: allow wireguard-go receive routines to log

Browse Source 
I've spent two days searching for a theoretical wireguard-go bug
around receive functions exiting early.

I've found many bugs, but none of the flavor we're looking for.

Restore wireguard-go's logging around starting and stopping receive functions,
so that we can definitively rule in or out this particular theory.
