uml: redo the calculation of NR_syscalls
Redo the calculation of NR_syscalls since that disappeared from i386 and
use a similar mechanism on x86_64.
We now figure out the size of the system call table in arch code and stick
that in syscall_table_size. arch/um/kernel/skas/syscall.c defines
NR_syscalls in terms of that since its the only thing that needs to know
how many system calls there are.
The old mechananism that was used on x86_64 is gone.
arch/um/include/sysdep-i386/syscalls.h got some formatting since I was
looking at it.
