Python2.6 pkg_resources allowing incompat versions

[Joshua Harlow]

Noticed the following:

[09:48:13] <@harlowja> Python 2.6.6 (r266:84292, Dec 19 2012, 19:54:30)
[09:48:13] <@harlowja> [GCC 3.4.6 20060404 (Red Hat 3.4.6-11)] on linux2
[09:48:13] <@harlowja> Type "help", "copyright", "credits" or "license" for more information.
[09:48:13] <@harlowja> >>> import pkg_resources
[09:48:13] <@harlowja> >>> r = pkg_resources.Requirement.parse( 'requests>=1.2.1,<=2.2.1,!=2.4.0' )
[09:48:13] <@harlowja> >>> x = '2.4.3'
[09:48:13] <@harlowja> >>> x in r
[09:48:13] <@harlowja> True
[09:48:33] <@harlowja> Python 2.7.10 (default, Jun 18 2015, 15:58:36)

[09:48:33] <@harlowja> >>> x = '2.4.3'
[09:48:33] <@harlowja> >>> x in r
[09:48:33] <@harlowja> False

The 2.6 version is fixed by upgrading setuptools, so that it will then work like the 2.7 version.

    Ensure setuptools is somewhat recent

    Due to bugs in older setuptools version parsing
    we need to set a relatively new version of setuptools
    so that parsing works better (and/or correctly).

    This seems especially important on 2.6 which due to
    a busted setuptools (and associated pkg_resources) seems
    to be matching against incorrect versions.

    Closes-bug: #1489969
