Remove containers from empty capture file
Remove containers from empty capture file

A recent sysdig change resulted in container info embedded in capture
files being reported as events. In turn, this caused some tests that
were depending on empty.scap not having any events to fail.

So recreate empty.scap from an environment where no containers were
running. As a result they won't be included in the capture file and
there won't be any container events.
