keep TMPDIR variable and location

[johrstrom]

We mount $TMPDIR directly to /tmp. We should likely preserve the environment variable and the location when running in the container. This is because $TMPDIR is a known documented environment variable and location, and if we have these funny mount points users may run into issues because they expect it to be valid when it isn't.
