rubocops/lines: disallow quictls dependencies in homebrew/core

QuicTLS is a fork of OpenSSL that adds support for QUIC. We'll probably
end up adding it to homebrew/core at some point (see
Homebrew/homebrew-core#134975), but I don't think we want to actually
use it as a dependency of any formulae in place of OpenSSL.

We ought to only allow it for software that actually require QuicTLS in
place of OpenSSL, but I'm not aware of any existing formulae that have
this requirement.
