Move examples directory from log/examples to log/_examples.
Directories and files starting with an underscore are ignored by the go
toolchain by default unless explicitly listed.
In particular no empty godocs are generated for the _examples directory.
However, we still want to ensure on CI that _examples build so, add
special make target build-examples and have all depend on it.
