Jochen Hoenicke e855c60529 Use bn_add instead of bn_addmod (#80) 
The bip32 private key derivation used bn_addmod to handle
wrap around.  This was never sufficient as bn_addmod uses only
bn_fast_mod, so an additional bn_mod is necessary.  The bn_fast_mod
helped when bn_mod was not side-channel safe.  Now that bn_mod uses
constant time code, we can get rid of the unnecessary bn_fast_mod
step and use bn_add instead of bn_addmod.
