Rachel Rice db58345bc6 Update selection_source for AWS ec2 startup script rule
The JSON payload for `ModifyInstanceAttribute` event currently looks like:
```
"requestParameters": {
  "attribute": "userData",
  ...
},
```

Updating the selection_source from `requestParameters.userData: "*"` to `requestParameters.attribute: "userData"` accordingly.

David Hazekamp bc26970596 fix(rule): lnx_dd_file_overwrite /bin symlinks
This rule is subject to false negatives for *nix distros which
alias /bin to /usr/bin.  By using endswith we can catch dd usage
for either /bin or /usr/bin.
