remove zeroize dependency

this is not so much a problem as a possible source of false security for
the readers. all secret keys we handle are serialized in some form, and
those serialization buffers are *not* zeroed out after use. zeroing our
raw buffers doesn't help much in that case, using a zero-on-free
allocator would be much more helpful.
