fork.2: EAGAIN is not reported when task allocation fails 

I am not sure why we have:

   "EAGAIN fork() cannot allocate sufficient memory to copy
    the parent's page tables and allocate a task structure
    or the child."

The text seems to be there from the time when man-pages
were moved to git so there is no history for it.

And it doesn't reflect reality: the kernel reports both
dup_task_struct and dup_mm failures as ENOMEM to the
userspace. This seems to be the case from early 2.x times
so let's simply remove this part.
