David Benjamin b3a7b51f18 Fix off-by-one in BN_rand
If BN_rand is called with |bits| set to 1 and |top| set to 1 then a 1 byte
buffer overflow can occur.

See also upstream's efee575ad464bfb60bf72dcb73f9b51768f4b1a1. But rather than
making |BN_rand| fail, be consistent with the |bits| = 0 case and just don't
set the bits that don't exist. Add tests to ensure the degenerate cases behave.
