Remove old JSON LD signature implementation

Only PeerTube was compatible with it, and the library has moved on
RsaSignature2018 and removed RsaSignature2017 support. We had to create
a dirty fork of the RsaSignature2017 branch, which is not ideal.

Now we use the Mastodon implementation, that most other AP
implementations that support JSONLD signatures use.
