Add definitions of system calls to catch in native NetBSD targets

Browse Source 
All platforms on NetBSD use a shared system call table, so use a
single XML file to describe the system calls available on each NetBSD
platform.

gdb/ChangeLog:

       * syscalls/update-netbsd.sh: New file.
       * syscalls/netbsd.xml: Regenerate.
       * data-directory/Makefile.in: Register `netbsd.xml' in
       `SYSCALLS_FILES'

# Usage: update-netbsd.sh <path-to-syscall.h>
# Update the netbsd.xml file.
#
# NetBSD uses the same list of system calls on all architectures.
# The list is defined in the sys/kern/syscalls.master file in the
# NetBSD source tree. This file is used as an input to generate
# several files that are also stored in NetBSD's source tree. This
# script parses one of those generated files (sys/sys/syscall.h)
# rather than syscalls.master as syscall.h is easier to parse.
