We haven't been guaranteeing Go compatibility of libcontainer, so I think we can just drop these deprecated functions, but not a strong opinion.

This function was added in f103de5, but no longer used since 06f789cf26774dd64cb2a9cc0b3c6a6ff832733bc (v1.0.0-rc6) Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
