05391da556 internal/pipewire: implement footer
The POD itself is serialised without requiring a special case, however its presence is only indicated by the difference in size recorded in the header and payload.

This performs the check within the bounds of the POD only. This was not caught since spa_dict was only used as the final struct field until now.

46fa104419 ldd: require absolute pathname
The sandbox which ldd(1) runs in does not inherit parent work directory, so relative pathnames will not work correctly. While it is trivial to support such a use case, the use of relative pathnames is highly error-prone and generally frowned against in this project. The Exec function remains available under the same signature until v0.4.0 where it will be removed.
