Fix handling of overridden paths from database

If the first time you run podman in a user account you do a
su - USER, and the second time, you run as the logged in USER
podman fails, because it is not handling the tmpdir definition
in the database. This PR fixes this problem.

vendor containers/common v0.11.1

This should fix a couple of issues we have seen in podman 1.9.1
with handling of libpod.conf.
