[PATCH] Again, do not change the mode of all directories below $HOME.

[Ralf Wildenhues]

* tests/CuTmpdir.pm (chmod_tree): Do not run chmod on undefined
argument, can happen when the build path contains spaces.
---

Hi Jim,

this fixes a regression of "make check" when source and build tree live
in a directory with spaces in the name.  The regression was introduced
some time after I posted a fix for the issue last time.

Cheers,
Ralf
