Upstream has an option to build using the system spdlog, which is 
perfectly reasonable. We should use that configure-time option.

There's no reason to also use downstream patches which can get out of 
date, just to remove source code that isn't used. Debian does this all 
the time, and it's one of the reasons it's so hard to understand 
anything at all about how Debian packages are constructed. Their 
rationale for doing so is, I think, that it offends their morality to 
know that the build system is at all capable of using vendored code.
