syscalls.2: Move system calls from discontinued ports out of main syscall list
Various ports that had their own indigenous system calls have been discontinued. Remove those system calls (none of which had manual pages!) to a separate part of the page, to avoid cluttering the main list of system calls. Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
