Error oci runtime error: exec: "/opt/dockerslim/bin/sensor": permission denied

Hi!
I downloaded latest dist for mac v1.17, cloned samples from docker-slim/docker-slim/tree/master/sample/apps/node and built image from Dockerfile docker build -t my/sample-node-app .
When i tried run ./docker-slim build --http-probe my/sample-node-app and got error:

MacBook-Pro:dist_mac alex$ ./docker-slim build --http-probe my/sample-node-app

Reproduce the failure with the mac v1.17 distribution, the sample/apps/node image, and the reported docker-slim build command. Start with master/commands/build.go around OnBuild and the sensor startup path shown in the stack trace; done means the instrumented container starts without the sensor permission-denied error.
