This is a fix for commit 2502da8170 ("bitbake.conf/pseudo: Switch from
exclusion list to inclusion list"), which forgot ${WORKDIR}/rootfs-dbg.

oe/rootfs.py's _setup_dbg_rootfs() builds the debug tree under
${WORKDIR}/rootfs (already included) and only renames it to
${WORKDIR}/rootfs-dbg as the very last step, so the rename itself
doesn't lose anything: pseudo's database is keyed by (device, inode),
not by path. But PSEUDO_INCLUDE_PATHS also gates whether pseudo
intercepts any *later* access made through the new path prefix, and
rootfs-dbg wasn't covered.

That silently broke image-combined-dbg.bbclass's combine_dbg_image(),
which runs under fakeroot in do_image:

  tar -C ${IMAGE_ROOTFS} -cf - . | tar -C ${IMAGE_ROOTFS}-dbg -xf -

The extracting tar's chown() calls into ${IMAGE_ROOTFS}-dbg fell
through to real, unprivileged syscalls instead of being faked by
pseudo, so files copied into rootfs-dbg silently ended up owned by the
build user instead of their correct target ownership.
