Attempt to fix CI (#111)

* Allow MIT-0 license

pixi v0.70.2 pulls in borrow-or-share via uv-resolver, which is
licensed as MIT No Attribution.

* Build package with rattler-build instead of pixi build

Invoke rattler-build directly on the recipe with --env-isolation none
so the build script inherits the host environment. The pixi build
backend isolates the environment, which prevented the GITHUB_ACTIONS
check in the recipe from applying the short CARGO_HOME path on CI.
This broke the Windows build once pixi v0.70.2 introduced a snapshot
file long enough to exceed MAX_PATH.

The c_compiler variant moves from the manifest to variants.yaml, and
the upload script now looks for packages in rattler-build's output
directory.
