Fix tmpdir location

Commit 2ebf355989eb92ac9967eceee0af14d39477afe0 moved the tmpdir
creation for various tasks into the task itself. In doing so, TmpDir
was called with a relative path; that was, however, is interpreted
relative to the working directory, violating the property that
our tool never write anything outside the local build root unless
explicitly asked to do so (by specifying the output path in an
install or install-cas invocation). Fix this, by calling the the
tmp-dir function that is storage-layout aware.
