runsc: Synchronize container metadata changes with a file lock.
Each container has associated metadata (particularly the container status) that
is manipulated by various runsc commands. This metadata is stored in a file
identified by the container id.
Different runsc processes may manipulate the same container metadata, and each
will read/write to the metadata file.
This CL adds a file lock per container which must be held when reading the
container metadata file, and when modifying and writing the container metadata.
