So it is sbuild who should manage mount in this rootfs. Not sure how 
this patch
influence on internal sbuild mount/unmount logic. But sbuild shouldn't 
left any
mounts without any errors. Do you have any packages failed to be built?

Are there any lost schroot sessions running before external rm you have 
issue
with? This can be checked with 'schroot -la' command.

You can also try to add some verbose to sbuild with following change:

diff --git a/meta/classes/dpkg.bbclass b/meta/classes/dpkg.bbclass
index bcc3f828..b54e3ab9 100644
--- a/meta/classes/dpkg.bbclass
+++ b/meta/classes/dpkg.bbclass
@@ -113,6 +113,8 @@ dpkg_runbuild() {
      DSC_FILE=$(find ${WORKDIR} -maxdepth 1 -name 
"${DEBIAN_SOURCE}_*.dsc" -print)

      sbuild -A -n -c ${SBUILD_CHROOT} \
+        -D \
+        --chroot-setup-commands="mount" \
          --host=${PACKAGE_ARCH} --build=${BUILD_ARCH} ${profiles} \
          --no-run-lintian --no-run-piuparts --no-run-autopkgtest 
--resolve-alternatives \
          --bd-uninstallable-explainer=apt \

This will be very helpfull to get some build logs from your setup.
