Valve became `!Sync` between 0.6.2 and 0.7

[Brendan Molloy]

Was this intentional? It seems that this commit causes the change though it's non-obvious to me why.

I am asking because it broke my code. 😄

Ah, no, that was not intentional! I believe that should be fixable by adding + Sync to

stream-cancel/src/combinator.rs

Line 117 in bdc6ef0

 fut: Option<Pin<Box<dyn Future<Output = bool> + Send>>>, 

Would you mind opening a PR?
