Merge casper-network#4677

4677: Re-generate chainspec.toml for EE test support r=jacek-casper a=jacek-casper

chainspec.toml.in is now packaged with the test support crate (instead of a symlink to to chainspec.toml) and a small build script was added to generate a local chainspec automatically during a cargo build.

Closes casper-network/casper-sidecar#285.
