Rollup merge of #96757 - jyn514:fewer-clippy-rebuilds, r=Mark-Simulacrum

Browse Source 
Don't constantly rebuild clippy on `x test src/tools/clippy`.

This happened because the `SYSROOT` variable was set for `x test`, but not `x build`.
Set it consistently for both to avoid unnecessary rebuilds.

This is a very small step towards https://github.com/rust-lang/rust/issues/76495.
