Export F_*64 definitions to userspace permanently. "ifndef" usage made it
vailable at all times to the userspace, and this change has actually broken
building strace with the latest kernel headers. There could be some debate
whether having these F_*64 definitions exposed to the user space 64-bit
applications, but it seems that were no harm (as they were exposed already
for quite some time), and they are useful at least for strace for compat
application tracing purposes.

Em... It seems it hasn't been in Arnd's tree for next. It should be in
stable 6.0.
