libuv: disable flaky darwin test and enable some tests on x64 darwin

[paparodeo]

test fails on darwin sometimes but will pass eventually

https://hydra.nixos.org/build/281912463/nixlog/234

enable x64 darwin tests that were disabled due to using an sdk < 10.15 now that it uses sdk 11

remove conditionally disabled tests which are already disabled by default

Things done

• Built on platform(s)
  • x86_64-linux

• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking

Reported upstream?

Reported upstream?

quite a number of tests seem quite unreliable and there are something like 50 tests disabled with a comment.

    # Sometimes: timeout (no output), failed uv_listen. Someone
          # should report these failures to libuv team. There tests should
          # be much more robust.

I don't want to volunteer to be the libuv maintainer at this time but perhaps will circle back at some point.

Intended to be fixed in libuv/libuv#4652, sorry for the inconveniences.

should disable test in the meantime -- while the failure rate on my machine is low it seems to fail regularly on hydra.

Would be better to backport the patch — it'll be noticed when updating, whereas a manually disabled test is unlikely to be.

it will prevent the auto-updater from updating the package as the patch will conflict

[edit] tho could conditionally disable with versionOlder

Thanks a lot for the cleanup!
