Allow `--only-files` et al. to function with 'leading dot' notation for files

Is your feature request related to a problem? Please describe.

The following works fine:

bundle exec brakeman --only-files foo,bar

The following does not:

bundle exec brakeman --only-files ./foo,./bar

The files are simply skipped.

Describe the solution you'd like

I'd like brakeman to support this kind of notation for files, as a lot of other tools do. This makes automation a lot simpler.

Describe alternatives you've considered

Currently using a shim script in our CI/CD setup to convert all filenames with leading dots to a notation without. This shim script could be discarded if brakeman supported 'leading dot' notation (not sure what the correct term is, relative path prefixed by current dir?).

Can you explain a little bit more what you are trying to achieve? 🤔

Are you saying Brakeman is running from the root of the Rails application, but some other tooling is passing in paths starting with ./? Even though those paths are in the current directory?

Yep.
