Subject: [PATCH 2/2] random: fix GCC 4.7 -Wuninitialized

For some reason, GCC 4.7 targeting X86 in the Android NDK 8e complained about
the fields in the "btrd" struct in the union in binomial_distribution
(boost/random/binomial_distribution.hpp) maybe being uninitialized in a call
to its copy constructor. So make sure these fields are initialized in all
cases.
