test_onion: Switch from AES256 to AES128.
...
AFAICT, if SHA256 is good enough, and secp256k1 is good enough, AES128
is good enough.

test_onion: always generate 0x2 keys.
...
This means they're 32 bytes, which works better for everything.

test_onion: generate onion in place.
...
Rather than keeping each hop, we can generate it in place since we only
need the first hop result.

test_onion: put padding at the front.
...
This means we can save the partial HMAC of the padding for each step,
rather than the padding itself, when generating it.
Each step now takes the *last*, not *first* part of the onion array.
