Subject: [PATCH] test: add upload of integration logs from TravisCI builds

This commit adds adds:

- Functionality to `gotest.sh` to log the output of `lnd` instances used for
  integration testing to file.

- Uploading of those log files to [termbin.com ](http://www.termbin.com) from
  TravisCI integration builds.

As an example of a build with this enabled, you can look at [this
build](https://travis-ci.org/samvrlewis/lnd/builds/286942025), which is a build
from my `ci_logging_test` branch. That branch has the same diff as my
`ci_logging` branch but with a small inclusion to allow TravisCI builds to work
(as I described in [my
comment](https://github.com/lightningnetwork/lnd/issues/302#issuecomment-335133834)
the other day). If you scroll to the end of the job logs where `RACE=false`
you'll see a `after_script` section with an output like this:

```
output0.log uploaded to http://termbin.com/aloqr
output1.log uploaded to http://termbin.com/3ggh
output2.log uploaded to http://termbin.com/abb9
output3.log uploaded to http://termbin.com/rk9j
output4.log uploaded to http://termbin.com/956p
output5.log uploaded to http://termbin.com/iwwt
```

Fixes #302.
