KNOWN_BUGS: remove two not-bugs
- 11.7 signal-based resolver timeouts
Not considered a bug anymore but just implementation details. People
should avoid using timeouts with the synchronous name resolver.
- 11.16 libcurl uses renames instead of locking for atomic operations
Not a bug, just a description of how it works
Closes #11032
