linux: Consolidate statfs implementations
The __NR_statfs64 syscall is supported on all architectures but aarch64, mips64, riscv64, and x86_64. And newer ABIs also uses the new statfs64 interface (where the struct size is used as second argument). So the default implementation now uses: 1. __NR_statfs64 for non-LFS call and handle overflow directly There is no need to handle __NR_statfs since all architectures that only support are LFS only. 2. __NR_statfs if defined or __NR_statfs64 otherwise for LFS call. Alpha is the only outlier, since it is a 64-bit architecture which provides non-LFS interface and only provides __NR_statfs64 on newer kernels (v5.1+). Checked on x86_64-linux-gnu.
