[mp3lame] Fix MinGW-w64 compatibility (#38995)
Fixes https://sourceforge.net/p/lame/bugs/487/, allowing mp3lame to be
built using the MinGW community triplets.

Patch copied from [Robert
Hegemann](https://sourceforge.net/u/robert/profile/)'s upstream patches:
https://sourceforge.net/p/lame/svn/6410/
https://sourceforge.net/p/lame/svn/6416/

- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- [ ] SHA512s are updated for each updated download.
- [ ] The "supports" clause reflects platforms that may be fixed by this
new version.
- [ ] Any fixed [CI
baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt)
entries are removed from that file.
- [ ] Any patches that are no longer applied are deleted from the port's
directory.
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is added to each modified port's versions file.
