Just like with the rustc-std-workspace-core, this needs a xargo patch.

As a temporary work-around, miri now installs my fork of xargo that has this issue fixed. Still keeping the issue open though to track removing that work-around.

skip Miri tests if the setup fails

Currently we are in a situation where Miri can be installed but `cargo miri setup` fails (due to rust-lang/miri#713).  That should not lead to hashbrown's CI failing.

This has been fixed by a new xargo release.
