gnu: Add python2-pathlib2.

Adding only the Python 2 variant, since for Python 3 our minimum version
is 3.4 which already includes this package as part of the standard library.

+    (description "The goal of pathlib2 is to provide a backport of standard
+pathlib module which tracks the standard library module, so all the newest
+features of the standard pathlib can be used also on older Python versions.
+
+Pathlib offers a set of classes to handle file system paths.  It offers the
+following advantages over using string objects:
+
+@enumerate
+@item No more cumbersome use of os and os.path functions.  Everything can
+be done easily through operators, attribute accesses, and method calls.
+@item Embodies the semantics of different path types.  For example,
+comparing Windows paths ignores casing.
+@item Well-defined semantics, eliminating any inconsistencies or
+ambiguities (forward vs. backward slashes, etc.).
+@end enumerate")
