Don't detach from container while copying files from it

Files copying from containers to host shouldn't be performed
in background, because corresponding states must ensure
that operation is completed. Also remove containers after
data is copied.

It's impossible to create a state which waits util the
command in container exits by using 'dockerng' module, for
details see this issue: https://github.com/saltstack/salt/issues/30199
