Add the given runtime path to the Mach-O.
 @example
  file.rpaths # => ["/lib"]
  file.add_rpath("/usr/lib")
  file.rpaths # => ["/lib", "/usr/lib"]
 @param path [String] the new runtime path
 @param _options [Hash]
 @return [void]
 @raise [RpathExistsError] if the runtime path already exists
 @note `_options` is currently unused and is provided for signature
  compatibility with {MachO::FatFile#add_rpath}
