[Buildroot] [git commit] infra: remove auto derivation of host dependencies

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=4bdb067e380e72c3a6cb9c6ccf3791a6cf8661e0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This feature consists in automatically deducing dependencies of a host
package from the dependencies of the target variant.

However, it causes some issues, and many host packages need different
dependencies than their target variants.

Now that host dependencies are explicitly set for all packages, we can
remove it.
