[bug#44269] [PATCH] gnu: Add eosio-cdt.

[jesse]

Hi all!

This is my first patch, I hope I'm doing it correctly.

The patch below adds the Contract Development Toolkit (compiler) for smart
contracts on the EOS blockchain. I also have a package for EOS itself that is
a bit more involved, so I'll submit separately.

Total package size is 607MB of which self is 329MB. It takes a while to
compile (about an hour on my i7 laptop).

Any feedback is appreciated. Thanks.

Jesse
