[LEDE-DEV] [PATCH] dnsmasq: write resolv.conf also when noresolv = 1

[Paul Oranje]

When UCI dhcp.dnsmasq.noresolv is true, dnsmasq ignores the (wan) resolv.conf
for upstream name resolution and the dnsmasq init script ialso skips writing
/tmp/resolv.conf (/etc/resolv.conf soft links that file).

Not using the local running DNS service when noresolv is true does not make
sence; the semantics of that config value do not imply this. With this patch
the init script also writes /tmp/resolv.conf when noresolv is true.

fixes FS#785

This patch replaces an earlier patch with subject
  dnsmasq: also write /tmp/resolv.conf when UCI dhcp.dnsmasq.noresolv is '1'
which is obsoleted because that subject was required to be shorter.
