sys/stat.h: fix missing struct timespec definition

This is a second attempt to fix a compilation failure involving a
missing struct timespec definition in some situation. Previous attempt
was following commit but it had undesirable side effects and was
reverted:

  657c4a9d6c fcntl.h: fix a missing `struct timespec` definition

A similar issue was identified and reported in glibc [1], and the fix
was to include the timespec definition if __USE_XOPEN2K8 was defined. To
minimize the possible impact of this new fix, it was decided to not
replace __USE_ATFILE by __USE_XOPEN2K8 as glibc did, but to add an
additional OR condition on __USE_XOPEN2K8.
