[Bootstrap] Update bootstrap nodes

[nurupo]

Hello,

We have just discovered a couple of bugs in Toxcore v0.2.2 that affect 
bootstrap nodes. You are likely to encounter them when updating to 
v0.2.2, so we decided to post workarounds to them until a new Toxcore 
version with the bugs fixed is released.

1. If you use DHT_bootstrap, it won't set the private key correctly. To 
fix that, apply this patch 
https://github.com/TokTok/c-toxcore/commit/c3baa1c24b3fe5fab6145e0268100ff3bfc21e39.patch

2. Build Toxcore using cmake and add -DUSE_STDERR_LOGGER=ON flag when 
running the cmake command, otherwise your bootstrap node will likely 
crash at run time. On how to build toxcore using cmake see 
https://github.com/TokTok/c-toxcore/blob/master/INSTALL.md. Here is a 
related bug report for this issue 
https://github.com/TokTok/c-toxcore/issues/879.
