[pipertts] Fix dependency unpack on Windows (#20362)

Override inherited maven-dependency-plugin execution `embed-dependencies`
to exclude native platform folders during unpack:

- **/win-*/**
- **/debian-*/**
- **/macos-*/**

This prevents unpacking macOS symlink entries that fail on Windows due to
missing symlink privileges. The resulting jar should not affected, as those
are excluded from packaging anyway.
