Fix restoring files as non-root user

As we cannot reliably detect in advance if we can set ownership, permissions,
timestamps or ext attributes, execute ALL the requested changes before
returning the first error we found.

Report total errors at end of restore and stop printing entire stacktraces
where just the error message is sufficient.

Fixes #655
