linux: Consolidate Linux getsockopt implementation
This patch consolidates the getsockopt Linux syscall implementation on sysdeps/unix/sysv/linux/getsockopt.c. 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.
Checked on x86_64-linux-gnu and i686-linux-gnu. </cut>
