Subject: misc/wasm: use temporary directory provided by Node.js
X-Git-Tag: go1.12beta1~301

misc/wasm: use temporary directory provided by Node.js

os.TempDir() did not return a proper directory on Windows with js/wasm,
because js/wasm only uses the Unix variant of TempDir.

This commit passes the temporary directory provided by Node.js to the
Go runtime by adding it as a default value for the TMPDIR environment
variable. It makes TempDir compatible with all platforms.

Fixes #27306.
