This is a bit opinionated, but some comments in integration tests do not
really help to understand the nature of the tests being performed by
stating something very obvious, like

	# run busybox detached
	runc run -d busybox

To make things worse, these not-so-helpful messages are being
copy/pasted over and over, and that is the main reason to remove them.

Move the repetitive code and comment into setup_netns.

...instead of an explicit or absent status check.

Commands that are not run via "run" helper (cat, mkdir, __runc)
do not set $status, so it makes no sense to check it.

This misleading comment is obviously a copy/paste from the previous
test. Fix it.

In our bats tests, runc itself is a wrapper which calls bats run helper,
so using "run runc" is wrong as it results in calling run helper twice.

The "runc delete --force [paused container]" test case does not check
runc pause exit code, and if added, the test fails in rootless tests,
because:
 - not all rootless tests have access to cgroups;
 - rootless containers doesn't have default cgroups path.

To fix, add:
  - setup for rootless case;
  - require cgroups_freezer;
  - runc pause exit code check.

This is mostly to improve readability. While at it, make the script more
robust by adding -e option to shell. The exception is echo $pid which is
opportunistic and may fail depending on the order of pids in the file.

Also, remove the empty comment and a shellcheck annotation.
