[Swan-dev] nsrun --ns overwriting host's /etc/ipsec.* files :(

I ended up a few times with test configs on my laptop's /etc/ipsec.* files.
I did some testing and found out that kvmrunner.py does not do this, but
nsrun --ns does. I made the host files immutable after restoring them and I
see this in the test when using nsrun:
Traceback (most recent call last):

bisecting this lead to this commit breaking it:
