Auto merge of #10154 - stjepang:fix-local-urls-only-10147, r=KiChjang

Fix #10147: Correctly handle flag local_urls_only

In function Request::fetch_main, flag local_urls_only (if set)
should allow fetching local urls only. Before this change, the flag had
the inverse behaviour.

Fixes #10147.
Test with: `./mach test-unit -p net fetch::test_fetch_with_local_urls_only`
