[PATCH] avoid use of undefined variable in warning

[Ralf Wildenhues]

* tests/CuTmpdir.pm (chmod_tree): Do not warn if $dir is
undefined.
---

Hi Jim,

I'm currently debugging my parallel Automake TESTS pending patch
using coreutils' test suite.  This turned up as side issue;
I haven't seen this show up otherwise.

I'll post patches when I get the bugs that I see ironed out.

Cheers,
Ralf
