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.
