Using current master, on Ubuntu 16.04 with Python 3.5, a startproject
command of the form:
`django-admin.py startproject --template=https://github.com/caktus/django-
project-template/zipball/master --extension=py,rst,yml
--name=Makefile,gulpfile.js,package.json newproject`
is failing with PermissionError:
{{{

--template=https://github.com/caktus/django-project-
template/zipball/master --extension=py,rst,yml

Inspecting the leftover extracted "archive" all files extracted have mode
000. Unzipping the leftover zipfile using the os unzip command results in
files that are "-rw-rw-r--".
This appears to be due to new code added for #26494 which is setting the
file mode based on the value of a zipinfo external_attr value...however in
my case this external_attr value is 0 and none of the extracted file can
subsequently be opened by the remainder of the startproject command code.
{{{

}}}
Setting as a release blocker since this is a regression from 1.10, where
the same command works fine. I think the fix for #26494 needs revisiting
since apparently external_attr isn't always usefully set (doc seems
nonexistent in Python for this attribute??).
