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.
