[Buildroot] [RFC PATCH v2 1/1] package/pkg-download: don't export the download command variables

[Dario Binacchi]

Exporting the download variables can cause unfortunate name clashes, as
occurred with the SCP variable used by Binman for compiling U-Boot [1].
Do not globally export the package download commands anymore; instead,
pass them to the dl-wrapper environment.
