Build step error in `citgm-smoker` configuration

The last build step in https://ci.nodejs.org/view/Node.js-citgm/job/citgm-smoker/configure generates the following error

+ find /home/iojs/tmp -mtime +3
+ xargs rm -rf
+ temp=/home/iojs/tmp/citgm_tmp
+ rm -rf '/home/iojs/tmp/citgm_tmp/*'
+ mkdir /home/iojs/tmp/citgm_tmp
mkdir: cannot create directory ‘/home/iojs/tmp/citgm_tmp’: No such file or directory
+ true

I think the issue is that the /home/iojs/tmp directory itself is deleted when the find /home/iojs/tmp -mtime +3 | xargs rm -rf command is executed. The problem then is that os.tmpdir() returns a directory that does not exists.

A quick fix might be to change find /home/iojs/tmp -mtime +3 | xargs rm -rf to find /home/iojs/tmp/* -mtime +3 | xargs rm -rf

Start with the citgm-smoker configuration at the linked CI job and inspect the cleanup commands shown in the build log. Check how os.tmpdir() is used, then verify the cleanup step leaves the temporary directory available and the final mkdir succeeds in a completed build.
