[git commit nptl] enable nanosecond stat support for everyone

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=0e591d0e1578883a25f9055f717a446d801ed733
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/nptl

Fill out the stat structure so that the nanosecond resolution support is
always available.  There is a small code size increase for a few ports
(three additional assignments in xstatconv), but otherwise everything
should remain the same.

While we're here, punt __old_kernel_stat from the few headers that still
define it as it is unused in uClibc and causes compile errors after these
nanosecond changes.
