The changes are: 1. Remove it from auto-generation syscalls.list on all architectures. 2. Add __ASSUME_GETSOCKOPT_SYSCALL as default and undef if for specific kernel versions on some architectures. This also fix a potential issue where 32-bit time_t ABI should use the linux getsockopt which overrides the underlying SO_* constants used for socket timestamping for _TIME_BITS=64.
