copy: require fiemap sync also for 2.6.38 kernels

* src/extent-scan.c (extent_need_sync): Require sync also for 2.6.38.
Without this, part of the cp/fiemap-empty test would fail both on
F15-to-be (2.6.38.1-6.fc15.x86_64) and rawhide.  For details, see
http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/22190
