[Buildroot] [PATCH] scipts/autobuild-run: properly import urllib2.URLError

[Yann E. MORIN <yann.morin.1998@free.fr>]

Commit 37766e9 (scripts/autobuild-run: add a retry loop to not fail on
urllib URLError) introduced an import of URLError, but that raises
exceptions in both python2 and python3:

    $ python2 -c 'import urllib2.URLError as URLError'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ImportError: No module named URLError

    $ python3 -c 'import urllib.error.URLError as URLError'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    ModuleNotFoundError: No module named 'urllib.error.URLError'; 'urllib.error' is not a package

The working solution is to import from:

    $ python2 -c 'from urllib2 import URLError; raise URLError(None)'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    urllib2.URLError: <urlopen error None>

    $ python3 -c 'from urllib.error import URLError; raise URLError(None)'
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
    urllib.error.URLError: <urlopen error None>
