Albert S db17e58deb Assign syscalls into groups. Add whitelist mode (default).
Classify syscalls into groups, for x86_64 only for now.
Up to date for 5.15, generate some #ifndef for syscalls
introduced since 5.10. Only support x86_64 therefore at this point.

Switch from blacklisting to a default whitelist.
