Bump libuv.

[maleadt]

Follow-up on #46796; now that all relevant PRs (notably libuv/libuv#3754) have been merged upstream, I've backported this to our branch, JuliaLang/libuv#32, and adapted to the API changes that were involved.

@simonbyrne This should fix the issue you encountered on a SLURM cgroup1 set-up, #46796 (comment); please verify.

@gbaraldi This also includes JuliaLang/libuv#29, which AFAIK you hadn't bumped to master yet?

It works! Many thanks @maleadt for seeing this through.

Thanks for verifying. CI failures look unrelated, so this seems good to go.

Looks like this PR did not update the source checksums for libuv.
