[pypy-issue] [issue1723] test runner filling temp directory with _testcapi modules

[mattip]

New submission from mattip <matti.picus at gmail.com>:

Every test run is recompiling _testcapimodule.c, filling up temp directory with 
many subdirs for each nightly buildbot run.
We should fix lib_pypy/_testcapi.py to use a hash like cffi does to build once 
for each version of pypy and c-files
We should also add a cleanup step to buildbot?
