imports: make tests compatible with modules

Tweak the goimports tests to be more module-compatible. This should be
the last big change to the tests; they all pass with the new
implementation.

The primary change is to avoid using packages not provided by the test's
modules. Other modules will be downloaded at test time, which is
nonhermetic and quite slow.

Other miscellanea:

- The appengine grouping tests have to be split out so
they can be GOPATH-only, because modules have to have dots in their
names.
- The tests for .goimportsignore and node_modules are GOPATH-only
because we decided not to include those behaviors in go/packages in
module mode.
- Some vendoring tests are GOPATH-only because vendoring is not a thing
in module mode.
- TestFindImportInLocalGoFiles changes content, because the existing
test was incorrect: bogus.net/bytes was a viable candidate even though
it isn't on disk. I'm not sure why it wasn't flaky.

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.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
