Checklist

• [x] Used a personal fork of the feedstock to propose changes
• [x] Bumped the build number (if the version is unchanged)
• [ ] Reset the build number to 0 (if the version changed)
• [x] Re-rendered with the latest conda-smithy (Use the phrase code>@<space/conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• [x] Ensured the license file is being packaged.

This removes the mingw compiler in favor of the default platform compiler, only adds openssl for unix where this is needed, and adds a THIRDPARTY license for any crates that sccache depends on.

• Selectors are suggested to take a <two spaces>#<one space>[<expression>] form. See lines [22]
