support/download: convert wget to use the wrapper
This drastically simplifies the wget helper, as it no longer has to deal with atomically saving the downloaded archive. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr> Tested-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> (Tested by running 'make busybox-source') Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
