go/packages: handle case when go list returns absolute ImportPath

go list -e, when given an absolute path, will find the package contained at
that directory. But when no package exists there, it will return a fake package
with an error and the ImportPath set to the absolute path provided to go list.
This change modifies the go list driver to convert that absolute path to what
its package path would be if it's contained in a known module or GOPATH entry.
This will allow the package to be properly "reclaimed" when overlays are
processed.

Fixes golang/go#33157

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

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.
