Subject: [PATCH] templates: collect generator output to list before adding to
 another list

When trying to generate a spec for git-machete:

$ py2pack generate git-machete -f git-machete.spec
generating spec file for git-machete...
Traceback (most recent call last):
  File "/usr/bin/py2pack", line 10, in <module>
    sys.exit(main())

    {%- set scripts_or_console_scripts = (
TypeError: unsupported operand type(s) for +: 'generator' and 'list'

Turns out the, setup.py declares scripts=['git-machete'], which makes jinja2 try
running an equivalent of `map(os.path.basename, scripts) + []`.
