bb/ui/crumbs/tasklistmodel: more robust checking for substrings

Relying on the count() method of Str to determine whether the string
contains a substring is error prone purely because the return value doesn't
strictly convert to a Boolean value.
To that end take the more pythonic approach of using the in operator (foo
in bar) to check for the substring.
Further, add a helper method for the common case of testing whether a pn
is -native, -cross or virtual/
