This fixes an issue where view source on a local file would return a blank page.
This fixes an issue where view source on a local file would return a
blank page.

This bug was introduced by the fix for issue 26129 (r30418), which
was to limit view source so that it wouldn't be able to load
javascript or data URLs, but that change forgot to allow file urls.

This fixes the above omission by allowing file URLs again.

TEST=works:view-source:file:///tmp/test.html, doesn't work:view-source:javascript:alert('foo')
