[Buildroot] [PATCH 1/2] host-cargo: select host-rustc

[Fabrice Fontaine]

Buildroot documentation specifies that cargo-based package should only
depends on BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and selects
BR2_PACKAGE_HOST_CARGO but this does not work as host-cargo depends on
BR2_PACKAGE_HAS_HOST_RUSTC which is selected only when host-rustc is
selected.

So instead of having to select both cargo and rustc in each cargo-based
package, replace BR2_PACKAGE_HAS_HOST_RUSTC dependency by
BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and select
BR2_PACKAGE_HOST_RUSTC
