Bryan C. Mills 1fd30d290b refactor/importgraph: set env from packagestest.Export and check errors from Build ... This test was written for GOPATH mode, and subsequently updated to use packagestest at a time when GO111MODULE defaulted to "auto" (in this case, off). As a result, the test was failing to set environment variables relevant to the test, such as GO111MODULE=off. The missing environment was causing errors that were subsequently masked by a missing error check: the errors returned by importgraph.Build were only read in an "if false" block. This CL adds the missing environment variables and error checks. Using the correct environment may or may not fix the observed test failures.
