test: handle chdir errors correctly

Browse source 
When we get to this code, we already updated the environment variables
so we need to use the usual error path to restore them.

And where chdir does fail, print an error to the log. 256 chars should
be enough here, if your tmpdir exceeds that you just have the error
message cut off.
