[Buildroot] [git commit branch/2018.11.x] support/download/dl-wrapper: fix urlencode option never being sent to backend

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=8e38dbeab1ae774fa048d87ae1d12ac4aa02841e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x

Since commit 38de434123 ("download: fix file:// BR2_PRIMARY_SITE
(download cache)"), the urlencode option is no longer passed to the
download backend, because we use ${backend} instead of
${backend_urlencode}.

We must get the urlencode information from backend_urlencode.
