metadata: change encryption mode names

As new encryption modes are being added to the kernel that use 128 bit
keys (see https://patchwork.kernel.org/patch/9741913), we will need the
encryption modes to be more descriptive.

This change breaks backwards compatibility for the protobuf, but that's
fine because we have not released yet.
