sysext: validate work directory metadata before removal

unmerge_hierarchy() joined the persisted work_dir value directly with
--root=. An empty value therefore resolved to the root itself and was passed
to rm_rf().

Require the decoded metadata to name a non-empty, safe, normalized relative
path before constructing the removal target. Add coverage using a disposable
root with deliberately emptied metadata.

Follow-up for 9cfad502f4aa103ef0d2191cbb6b82fecfbc5044
