[FS#847] resolv.conf no longer points at local dnsmasq instance

[LEDE Bugs]

The following task has a new comment added:

FS#847 - resolv.conf no longer points at local dnsmasq instance
User who did this - Paul Oranje (por)

----------
First, I understand that the commit has been reverted - way to many problems.

Second, I found the cause of the problem Kevin encountered, it is in dnsmasq_ismain().
The line
[ -n $notinterfaces ] && list_contains notinterfaces "loopback" || return 1
should be
[ -n $notinterfaces ] && list_contains notinterfaces "loopback" && return 1

(it looks like something went wrong in my work-flow, between test and commit, I'm truly sorry).

Last, about who made the remark on possible DNAT rewrites of the port listened on, I was mistaken, it was Hans, not Kevin, who made that remark.
