Handle 64-bit attestation values on 32-bit platforms.

The BN_set_word OpenSSL function takes an unsigned long, which on 32-bit
platforms (like fugu) is 32 bits, causing 64-bit values to be
truncated.  This CL adds a function that handles the conversion
correctly on 32-bit platforms, and fails hard on platforms whose
unsigned long is neither 64 nor 32 bits.
