As ptxdist/projectroot/etc/dnsmasq.conf was once copied from dnsmasq source
tarball and as it really entirely commented out I decided to remove it from
ptxdist's projectroot. Now it is copied directly from dnsmasq source, so it
is always up to date - althouth still as empty as it always been.

It is done in this very patch as help text changed as well, explaining
BSP author needs to provide such a config anyway.

Of course I'm fine splitting the patch in two if there is an agreement
this is way to go. An alternative would be to use install_replace and
Kconfig entries, but given number of config options I'm not really
convenient with this idea.
