.travis.yml: fix travis CI

Changes made:
* Call autogen.sh before building protobuf.
It's unclear how this worked before, but the README instructions for
protobuf does state to run autogen.sh prior to building and installing.
* Fix downloadArchive to take in a prefix path rather than the number of
prefix directories to skip. The reason for this change is due to a bug
in the Go build system where unexpected directories were being packed.
See https://golang.org/issue/29906
* Explicitly set Travis dist to be "xenial", which comes with Go1.11.
We require Go1.11 for two reasons:
	* The use of t.Helper in integration_test.go
	* Proper understanding of the -mod=vendor flag
	(even if all that flag does is disable modules).
* Add a hack to integration_test.go to periodically output the timestamp
to work around a restriction in Travis where it auto-kills the test
after 10 minutes of no stdout activity.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
