bitcoin-classic: remove

Motivations:

  1. The project having been closed for 5 years,
  2. 1 BXC is now worth less than 1 ¢,
  3. It will stop building once Qt 5.14 is removed.

-      Bitcoin is a free open source peer-to-peer electronic cash system that is
-      completely decentralized, without the need for a central server or trusted
-      parties. Users hold the crypto keys to their own money and transact directly
-      with each other, with the help of a P2P network to check for double-spending.
-
-      Bitcoin Classic stands for the original Bitcoin as Satoshi described it,
-      "A Peer-to-Peer Electronic Cash System". We are writing the software that
-      miners and users say they want. We will make sure it solves their needs, help
-      them deploy it, and gracefully upgrade the bitcoin network's capacity
-      together. The data shows that Bitcoin can grow, on-chain, to welcome many
-      more users onto our coin in a safe and distributed manner. In the future we
-      will continue to release updates that are in line with Satoshi’s whitepaper &
-      vision, and are agreed upon by the community.
