[git commit 0_9_30] enable nanosecond stat support for everyone

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=35a5b86ad1d7b806cdea6cbf0d1101d16ad3dd25
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/0_9_30

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.

Patch is too large, so refusing to show it
