wavpack: Upgrade 5.6.0 -> 5.8.1 to allow CMake 4+ compatibility

- Drop patches becaus already fixed in the newer version.
- The LICENSE file has changed so updated LIC_FILES_CHKSUM to match the new md5sum.

Changelog:

https://github.com/dbry/WavPack/blob/5.8.1/ChangeLog

Fix:

| CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
|   Compatibility with CMake < 3.5 has been removed from CMake.
|
|   Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
|   to tell CMake that the project requires at least <min> but has been updated
|   to work with policies introduced by <max> or earlier.
|
|   Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.
|
|
| -- Configuring incomplete, errors occurred!
