Subject: [PATCH] Drop support for Go 1.11.

The protobuf 1.3.3 depends on Go interpreter of at least 1.12. Per the
Go version support policy (two releases before the current release of
1.14), this version is unsupported anyway. This commit drops support for
1.11 and expands the test matrix to cover 1.13 and 1.14.
