[tor-relays] new VPS bridge bandwidth under-reported

[starlight.2015q1 at binnacle.cx]

Oops.  The "rate limit" I quoted
is actually the limit on the DOCSIS
modem here, not on the VPS.  Probably
not 'iptables' traffic shaping
after all.

Using 'speedtest_cli.py' the max rate
has been showing 100 Mbits/sec, but
I discount that because the speedtest
node appears to reside in the same
data center as the VPS and is probably
on the same LAN.

Nonetheless, the Tor bridge is showing
a ridiculous low bandwidth value and
it seems reasonable to figure out
why.
