submodule: Bump RLS to ff0b9057

[Xanewok]

No functional changes (except introducing user-configurable crate_blacklist), most importantly bumps RLS version to 1.38 to match the current nightly version.

@Xanewok I can only rubber stamp this PR... I cannot actually review it, so I prefer that you r? @ghost and r+ it yourself instead.

[Xanewok]

I can guess that r?ing @ghost is so that highfive doesn't assign other people? Should I then r? myself in these cases?

Depends on whether you fancy more emails from GitHub or not ;)

🔒 Merge conflict

This pull request and the master branch diverged in a way that cannot be automatically merged. Please rebase on top of the latest master branch, and let the reviewer approve again.

How do I rebase?

Assuming self is your fork and upstream is this repository, you can resolve the conflict following these steps:

1. git checkout update-rls (switch to your branch)
2. git fetch upstream master (retrieve the latest master)
3. git rebase upstream/master -p (rebase on top of it)
4. Follow the on-screen instruction to resolve conflicts (check git status if you got lost).
5. git push self update-rls --force-with-lease (update this PR)

You may also read Git Rebasing to Resolve Conflicts by Drew Blessing for a short tutorial.

Please avoid the "Resolve conflicts" button on GitHub. It uses git merge instead of git rebase which makes the PR commit history more difficult to read.

Sometimes step 4 will complete without asking for resolution. This is usually due to difference between how Cargo.lock conflict is handled during merge and rebase. This is normal, and you should still perform step 5 to update this PR.

Error message

warning: Cannot merge binary files: Cargo.lock (HEAD vs. heads/homu-tmp)
Auto-merging Cargo.lock
CONFLICT (content): Merge conflict in Cargo.lock
Automatic merge failed; fix conflicts and then commit the result.
