Fix a possible memory leak in req_main
if the private key is output to stdout using the HARNESS_OSSL_PREFIX,
out is a stack of BIOs and must therefore free'd using BIO_free_all.
Steps to reproduce:
$ HARNESS_OSSL_PREFIX=x OPENSSL_CONF=apps/openssl.cnf util/shlib_wrap.sh apps/openssl req -new -keyout - -passout pass: </dev/null
[...]
