Updated manifest detection in classify.py to use dynamic handler-based patterns

Replaced the _MANIFEST_ENDS list in summarycode/classify.py , that was a hardcoded list of extensions with a dynamically generated set of manifest file extensions derived from APPLICATION_PACKAGE_DATAFILE_HANDLERS.

It will ensures that the is_manifest classification flag uses latestt and comprehensive patterns that are being defined across all supported package handlers.
