[Buildroot] [PATCH v2] Package downloads: allow restricting to primary site only

[Thomas De Schampheleire]

This patch adds a new config option BR2_PRIMARY_SITE_ONLY that, when set,
restricts package downloads to the specified BR2_PRIMARY_SITE. If the package
is not present on the primary site, the download fails.

This is useful for project developers who want to ensure that the project can
be built even if the upstream tarball locations disappear.
