libcontainer: Add option for pre-mounted runfs path

This allows the user to specify a path for the directory
in which they want the container to run. It also allows
the user to specify the path to the pid file.

BUG= chromium:628373 
TEST=Create a directory, bind mount the container rootfs
to the new directory, use container_config_premounted_runfs
and container_config_pid_file_path.
