perf bpf augmented_raw_syscalls: Add an assert to make sure sizeof(saddr) is a power of two.
We're using the BPF verifier suggestion: 22: (85) call bpf_probe_read#4 R2 min value is negative, either use unsigned or 'var &= const' That works only when const is a (power of two - 1) so add an assert to make sure that that is the case.
