Shrink space needed by undefined syscalls in syscall tables.
Undefined syscall looked like this before this change:
{ 5, 0, printargs, "SYS_53" },
That is, "SYS_53" string had to be allocated and stored in strace binary.
Since now SCNO_IN_RANGE() macro requires sysent[scno].sys_func != NULL
for valid syscalls, we can replace printargs with NULL in such lines
and make them "invalid", thus not requiring syscall name string.
Savings on i386:
text data bss dec hex filename
237389 704 18944 257037 3ec0d strace.before
236973 704 18944 256621 3ea6d strace
Savings on mips:
336551 153692 38320 528563 810b3 strace.before
275543 153688 38320 467551 7225f strace
Tested to still decode undefined syscalls correctly (syscall no. 222 on i386).
* linux/*/syscallent.h: Replace 'printargs, "SYS_nnn"' with
'NULL, NULL'.
