move ppp script to upstart

Binary package hint: ppp

Hi.
I created the following ppp-dns.conf for upstart:

# Restore /etc/resolv.conf if the system crashed before the ppp link
# was shut down.
#

description "Restore /etc/resolv.conf if system crashed"

start on (local-filesystems
          and gdm)

script
        test -x /etc/ppp/ip-down.d/0000usepeerdns && /etc/ppp/ip-down.d/0000usepeerdns
end script
