criu swrk is a special mode when we don't want to execute a service,
but want to use RPC.
Here is more details:

Another good feature of this mode is that we don't need to create
action scripts and we will be able to remove the hack with saving StdFds.
criu swrk is supported starting with CRIU 1.5.1.

We need this to unmask syscall.ESRCH error, which handled in docker and
can be handled by other clients.
Closes#457

Currently we have a problem when buffers are used for std file
descriptors. These buffers are filled from goroutines (Cmd.goroutine),
and we need to wait them to be sure that all data have been copied.
