[coreutils] [PATCH] maint: update to latest gnulib

[Eric Blake]

* gnulib: Update to latest.
* bootstrap.conf (gnulib_modules): Add fdutimensat.
* src/touch.c (touch): Use fdutimensat instead of gl_futimens.
---

In light of Paul's desire to use fdutimensat in tar, this is
the matching change to get coreutils to use it.  Okay to apply?
