test if TMPDIR is accessible before using
Private temporary directories as created by e.g. libpam-tmpdir are nice, but they are also very effective in preventing our priviledge dropping to work as TMPDIR will be set to a directory only root has access to, so working with it as _apt will fail. We circumvent this by extending our check for a usable TMPDIR setting by checking access rights. Closes: 765951
