[pypy-dev] os.tmpnam warnings

[Da_Blitz]

Hi

pypy 1.5 does not display a warning when using the os.tempnam and 
os.tmpnam functions. use of these functions is not recommended as they 
can cause security issues and hence python issues a RuntimeWarning


below is a patch to app_posix.py to make it act more like cpython
