Test suite creates temp files with fixed path

[dcollinsn]

Hello,

Please see the following test failure:

`Output from './Build test':

t/003_helper.t ....... ok
t/001_load.t ......... ok

Failed test 'use Catalyst::Test;'

at t/005_memory_leak.t line 9.

Looks like your test exited with 255 just after 1.

t/005_memory_leak.t ..
Dubious, test returned 255 (wstat 65280, 0xff00)

This occurs because your testsuite attempts to create a temporary directory with a hardcoded name (specifically, /tmp/TestApp). However, if another user has already built your module on the same computer, it will be impossible to access that directory. Please consider using a non-hardcoded name for your top-level temporary directory.
