lrzip -t file.lrz fails when run from write-protected dir

[pete4abw]

See This issue for more details

A possible solution is to change the DEFAULT temporary directory from $PWD to /tmp. lrzip-next handles the temp files a little differently, but the problem is the same. Proposed patch is attached. Interestingly, when running through tar -I lrzip.651 -tf file.lrz the error does not occur.
