fix generating syscall-names.h
Sometimes the syscall number is not defined with a number but with an
offset to an other syscall and then make_syscall_h.sh created some
broken header file.
For example the bit/syscall.h from musl for i386 has this:
#define __NR_timer_create 259
#define __NR_timer_settime (__NR_timer_create+1)
With this patch the resulting array looks like this:
[259] = "timer_create",
[(__NR_timer_create+1)] = "timer_settime",
This fixes this bug from OpenWrt:
