DNSMASQ runs as user nobody per design of dnsmasq devs.
from the manpage:
-u, --user=<username>
Specify the userid to which dnsmasq will change after startup. Dnsmasq must
normally be started as root, but it will drop root privileges after startup by
changing id to another user. Normally this user is "nobody" but that can be
over-ridden with this switch.

Title:
network-manager no longer restarts dnsmasq
Status in network-manager package in Ubuntu:
New
Bug description:
restarting Network Manager does not have any effect on it's child
dnsmasq (nor does stopping and starting)
ubuntu@ubuntu:~$ pidof dnsmasq
2355
ubuntu@ubuntu:~$ sudo systemctl restart NetworkManager
ubuntu@ubuntu:~$ pidof dnsmasq
2355
This problem started in 15.10 and still exists in 16.04 beta2 - it
works as expected in 14.04.
The upshot is you cannot load any extra dnsmasq configuration set in
the conf dir /etc/NetworkManager/dnsmasq.d/ because dnsmasq doesn't
get restarted.
(As a related issue dnsmasq is also running as 'nobody' and I don't think it
should, Bug #1105493)
