Subject: [PATCH] [illumos] use pipe2 to create anonymous pipes

pipe2 allows the newly-created pipe to atomically be CLOEXEC.

pipe2 was added to illumos a long time ago:
https://github.com/illumos/illumos-gate/commit/5dbfd19ad5fcc2b779f40f80fa05c1bd28fd0b4e.
I've verified that this change passes all tests.
