veyron/services/identity:  Put the test cert.pem and key.pem in $TMPDIR.

Currently the cert.pem and key.pem that get generated by the test
identityd server get dumped into the current working directory.

This CL generates those files in a temp directory, and returns the name
of the files to the caller.
