cgroup mounts should happen before ContainerApiImpl initialization.

ContainerApiImpl factory method expects cgroups to be mounted therefore
when doing machine initalization we have to mount them first.

This fixes issue #33.
Prevent nscon/cli objects from linking in liblmctfy.a

generated liblmctfy.a. This prevents linking of liblmctfy.a into a binary that
defines its own main().

Closes #32
