Detect Django when requirements.txt is not in the project root.

[janimo]

Change Summary

Improve Django scanner.

What and Why:

Often the generated requirements.txt file contains only -r requirements/dev.txt or similar so there is no 'django' string in it.

How: Add another check for requirements.txt in immediate children of root dir. Not looking only for requirements/requirements.txt there could be other namings too.
