Fall back to using the kernel version for the OSRELDATE when

Browse Source 
/usr/include/osreldate.h doesn't exist on the system.  While this
could be worked around by saying something like 'make includes
OSLRELDATE=0' when this file doesn't exist, it is just as easy to
provide a fallback when the file we know we depend on doesn't exist.
While this doesn't make all targets work w/o a
/usr/include/osreldate.h, because some of the FreeBSD bootstrap tools
use this file.  'make includes' however does work.

Noticed by: peter, obrien (and likely others)
Pointy hat to: imp (for suggesting a method that depended on /usr/include)
