Remove user/group from dnsmasq config

In the case that FTL is started under root, dnsmasq changes the user to
pihole due to this setting. The shared memory is created before this
switch, and may cause issues such as failing to delete or reallocate
the shared memory.

These config lines were necessary before dnsmasq became part of FTL, but
now since dnsmasq runs under FTL, we can configure the user/group
through FTL.
