[warrior 24/32] cve-update-db-native: clean up proxy handling

[Armin Kuster <akuster808@gmail.com>]

From: Ross Burton <ross.burton@intel.com>

urllib handles adding proxy handlers if the proxies are set in the environment,
so call bb.utils.export_proxies() to do that and remove the manual setup.

(From OE-Core rev: 6b73004668b3b71c9c38814b79fbb58c893ed434)
