Fix internal header include paths. (#1011)

The extra leading `"CLI/"` part of include directives prevents the
inclusion of `CLI.hpp` from a relative directory without an extra `-I`
or `/I` compiler directive, and makes it harder to make CLI11 part of a
larger codebase.

This is a regression of #475.
