[Firehol-support] running FireHOL under busybox's ash-shell

[c.gatzemeier at web.de]

I'm trying to use FireHOL on an embedded wireless router (OpenWRT). So far I 
could patch it substituting all commands to those available on the router.

Now I ran into the following: 

The ash shell complains about unexpected "("s behind the "=" on lines like 
these:

work_realcmd=("(unset)")

local -a inlog=(loglimit "'IN-${work_name}'")

I don't know how this could be handled. I had just striped the outer () of the 
first line, but I guess that's not what was really intended.

Kind Regards,
Christian
