Migrate vcstool to use vcs2l shim

[traversaro]

The old vcstool is not compatible with recent setuptools. To deal with that, in vcs2l a vcstool shim was added in ros-infrastructure/vcs2l#94, and it provides the same python3-vcstool package for apt debian metadata.

As in conda we do not have the Provides3: python3-vcstool and Replaces3: python3-vcstool metadata capability, to provide the same behaviour we just transform vcstool >= 1.1.7 in being a simple noarch: generic shim that depends on the vcs2l package with the same version.

Users that need to be compatibility with older vcstool can just pin the vcstool version to vcstool < 1.0.0.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe/meta.yaml:

• ℹ️ top-level output has some malformed specs:

• In section run: vcs2l $1.1.7.*
  Requirement spec fields should match the syntax name [version [build]]to avoid known issues in conda-build. For example, instead of name =version=build, use name version.* build. There should be no spaces between version operators and versions either: python >= 3.8 should be python >=3.8.

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you but ran into some issues. Please check the output logs of the GitHub Actions workflow below for more details. You can also ping conda-forge/core (using the @ notation) for further assistance or you can try rerendering locally.

The following suggestions might help debug any issues:

• Is the recipe/{meta.yaml,recipe.yaml} file valid?
• If there is a recipe/conda-build-config.yaml file in the feedstock make sure that it is compatible with the current global pinnings.
• Is the fork used for this PR on an organization or user GitHub account? Automated rerendering via the webservices admin bot only works for user GitHub accounts.
