[OE-core] [PATCH] lib/oe/distro_check: Remove '_proxy' on dict values used by urllib.open

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

There are two ways to pass the proxies values into urllib.open: exporting
the environment variables *_proxy and passing as dictionary into the
urllib.open call. The latter is currenty used and values should not have
the '_proxy' string, so removing it. Also, ignore uppercase proxies, these
are not taken into account by the library.

Tested on a network with proxy, adding 'inherit +="distrodata"' on local.conf
with the following commands

    for distrotask in distrodataall distro_checkall checklicenseall; do
        bitbake universe -c $distrotask
    done
