Remove the build CI task now

It's identical to test, except it doesn't grab Foundry nor spawn a 
Monero regtest daemon. It doubles the amount of time test takes though, 
as it's doing everything twice.

While it may have value as a component, we're not using it like that 
right now, and if desired, we could add it back. While it may have value 
to produce binaries, we're note doing that either, and it wasn't 
building in release.
