buildsys: gen_bits_syscall_h: do not leave undefined SYS_xxx around
If we end up doing '#undef __NR_xxx', we don't want to leave the
corresponding SYS_xxx symbol defined. So undef it too.
For example, with the ARM EABI layer, we have a bunch of legacy
syscalls that we define early on and then later undefine (such
as __NR_utime). But we left SYS_utime defined so code that tests
for that define before using it would be broken (since it'd be
defined to a non-existent symbol).
