Prefer `require_relative` for internal requires

Due to the way rubygems monkey-patched require interacts with default
gems, and given that bundler is a default gem, and that bundler
manipulates the LOAD_PATH in very intricated ways, we can reduce the
risk of "leaking" to a different copy of `bundler` by using
`require_relative` for internal requires.
