analyzer/files: handle non-analyzer names in describe_file()

Browse source 
When a fa_file object is created through the use of Input::add_analysis(),
the fa_file's source is likely not valid representation of an analyzer's
tag and a Files::describe() should not error and instead return an empty
description.

Add a new Analyzer::is_tag() helper that can be used to pre-check `f$source`.

This isn't an actual pdf, but it shows in files.log as such :-)
