cmake: report whether we are using sub-second stat information Depending on the platform and on build options, we may or may not build libgit2 with support for nanoseconds when using `stat` calls. It's currently unclear though whether sub-second stat information is used at all. Add feature info for this to tell at configure time whether it's being used or not.
