godoc: add alt attr to gopher on main package index

The gopher with a miner hat on /pkg had no alt attribute
so screen readers would announce the image by its filename.
As the image is purely decorative, adding the empty string
as alternative text prevents the image from being announced.

For golang/go#22171

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
