symbolic link in directory where witness run executed leads to failure

[ChaosInTheCRD]

I added a symbolic link to README.md in this very repository after moving it into the docs directory. By coincidence I ran witness run in the directory and got the following failure.

➜ go run . run -s build -a environment -k buildkey.pem -o build-attestation.json -- \         
bash -c "echo 'hello' > hello.txt"
INFO    Starting environment attestor...             
INFO    Starting material attestor...                
ERROR   Error running material attestor: EvalSymlinks: too many links 
ERROR   failed to run attestors: EvalSymlinks: too many links 
exit status 1

Putting this issue here for me to pick up in a little bit.
