sys: use kernel headers instead of host headers
...
This solves several problems:
- host usually have outdates headers, so previously we need to define missing consts
- host may not have some headers at all
- generation depends on linux distribution and version
- some of the consts cannot be defined at all (e.g. ioctls that use struct arguments)

WUNTRACED wait returns when child has stopped.
That's not what we want to wait for.
If it's stopped we need to timeout wait and kill
the stopped child.

sysgen: pull in syscall numbers from kernel headers
...
Syscall numbers for different architectures are now pulled in
from kernel headers. This solves 2 problems:
- we don't need to hardcode numbers for new syscalls (that don't present in typical distro headers)
- we have correct number for different archs (previously hardcoded numbers were for x86_64)
This also makes syscall numbers available for Go code, which can be useful.
