build: avoid double-close bug with pipe2

Based on Coverity's finding on the previous patch, I audited
gnulib's pipe2 code and found that we had the potential for
a subtle double-close bug, unless gnulib guarantees that the
contents of the fd array are unchanged on pipe2() failure.

* .gnulib: Update to latest, for pipe2 fix.
