pixi build - pointing to recipe.yaml always rebuilds

[wolfv]

Checks

• [x] I have checked that this issue has not already been reported.

• [x] I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

When pointing to a folder that contains a recipe.yaml everything is fine because the lockfile says:

      - conda: ./recipe
...
- conda: ./recipe/recipe.yaml
  name: with-variants
  version: 0.1.0
  build: py310hd06803d_0
  subdir: osx-arm64
  depends:
  - python_abi 3.10.* *_cp310
  input:
    hash: '0000000000000000000000000000000000000000000000000000000000000000'
    globs:
    - recipe.yaml

However, when pointing to a recipe.yaml directly then the lockfile will say:

      - conda: ./recipe/recipe.yaml <- note the extra `recipe.yaml` here!
...
    globs:
    - recipe.yaml

Which will cause it to always rebuild. Maybe the globs in this case should say ../recipe.yaml? Or maybe we should find that if it's a file, we resolve to the parent directory?

Issue description

Pixi rebuilds the recipe every time.

Expected behavior

Not rebuild everytime.
