CL 129063 added a test in TestScript/mod_enabled, which was failing on Plan 9. The test was failing because the Init function of the cmd/go/internal/modload package was expecting ModRoot to be part of os.TempDir. However, ModRoot was set to TMPDIR, while os.TempDir is returning /tmp on Plan 9. This change fixes the implementation of os.TempDir on Plan 9 to handle the TMPDIR environment variable, similarly to Unix. Fixes #27065.
