syscalls.h: slightly reduce the jungles of macros
a) teach __MAP(num, m, <list of type/name pairs>) to take empty list (with num being 0, of course) b) fold types__... and args__... declaration and initialization into SYSCALL_METADATA(num, ...), making their use conditional on num != 0. That allows to use the SYSCALL_METADATA instead of its near-duplicate in SYSCALL_DEFINE0. c) make SYSCALL_METADATA expand to nothing in case if CONFIG_FTRACE_SYSCALLS is not defined; that allows to make SYSCALL_DEFINE0 and SYSCALL_DEFINEx definitions independent from CONFIG_FTRACE_SYSCALLS. d) kill SYSCALL_DEFINE - no users left (SYSCALL_DEFINE[0-6] is, of course, still alive and well).
