Instead of using the 'temp' and
'tempdir' DSL directives to create
temporary files, use fixed paths relative to __STATEDIR__. This has two
advantages:
1) The files are automatically cleaned up if the tests fail (and even if
that doesn't work they're easier to clean up manuall)
2) When debugging tests it's easier to figure out which of the temporary
files are relevant to whatever's going wrong

It looks a bit random to me, but anyway all those go away with your
(much needed) patch "test: Simpler termination handling for UDP tests",
so I'm also fine to apply it like that.
