[tor-browser-bundle/maint-4.0] Remove default obfs3 bridges #4 and #5, and scramblesuit bridge #1.

These bridges were removed because: 1. They have never provided their bridge descriptors for metrics. See #13504: https://bugs.torproject.org/13504 2. They are either unreachable or unreliable. 2.a. The two obfs3 bridges are unreachable: Oct 21 20:25:53.000 [warn] Proxy Client: unable to connect to 209.141.36.236:45496 ("TTL expired") Oct 21 20:25:53.000 [warn] Proxy Client: unable to connect to 208.79.90.242:35658 ("TTL expired") 2.b. The scramblesuit bridge is rejecting connections: Oct 21 20:26:57.000 [warn] Proxy Client: unable to connect to 188.40.121.112:39707 ("Connection refused") * REMOVE default bridges obfs3.4, obfs3.5, and scramblesuit.1. * RENAME other bridges' preference names to keep the lists sequential. * FIXES part of #13504, sort of kind of.
