pid1: lower log level if BPF LSM is not available

Currently, if you boot PID 1 in a container you always see a complaint
that BPF LSM won't work. That's fine, and log worthy, but probably not
above debug level. After all this is a really common case, and we should
gracefully adopt to our execution environment.
