[Firehol-devs] running 'debug' as non-root user

[Andrew Schulman]

When a firehol user is developing a config file and just wants to test their config with 'firehol.sh debug', they should
be able to run firehol as a regular user, i.e. not as root.  This is good practice.

Using firehol 1.260, when I try to do this, firehol first complains that I'm not root-- noisy, but harmless.  But then
it quits because it can't save the existing firewall rules.  But since I'm running 'debug', that shouldn't matter; I'm
not going to change the firewall.

The patch below fixes this problem and allows me to run 'firehol debug' as a non-root user.

Andrew.
