BCCSP is logging the following message:
[BCCSP_FACTORY] GetDefault -> WARN 29a Before using BCCSP,\
 please call InitFactories(). Falling back to bootBCCSP.

If it is not initialized manually. Gossip uses BCCSP's hash
so when running the intensive gossip_test, there are lots of
BCCSP log entries logged.
I added a line that initializes the BCCSP to prevent this.
