We used to collect all binaries into the `bin/` directory. However this led to confusions since certain commands where available both as `revng-command` and `revng command`. This commit moves all the executables except `revng` into `libexec/revng`, which, according to FHS, is dedicated to "internal binaries that are not intended to be executed directly by users or shell scripts".
