virtcontainers: Move unit tests for types/sandbox.go

Move unit tests that were in virtcontainers/sandbox_test.go relating
to Socket, Volume, and SandboxState to types/sandbox_test.go.

Change testSandboxStateTransition function to use SandboxState only
instead of Sandbox from virtcontainers/sandbox.go.

Fixes #435
