[Buildroot] [git commit branch/2022.02.x] package/zziplib: fix static build failure with mpd

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=43fd3fd836d142a7c5d16c8b25366d59bdb6d8fc
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

The current released version of zziplib copies static libraries with appended
major version, but omits creating the necessary links to the base file names.
This prevents the linker to find the libraries via the search path.

The issue (https://github.com/gdraheim/zziplib/issues/117) has been
fixed upstream; this patch extracts the necessary part of commit 0e8d35f92efb680c81f6ec1fca9f11d173dce389, to enable creation of symlinks.

This resolves the following autobuild issues:
