[Buildroot] [PATCH] package: Introduce $(2)_INFRA_EXTRA_DEPENDENCIES

[Maxime Hadjinlian]

Instead of repeating the filter-out function to remove the host-package
that we don't want as dependencies in each infra, handle it it
pkg-generic through a generic variable, which is specified by each
infra.

The $(2)_INFRA_EXTRA_DEPENDENCIES contains the specific host package
that we want to filter from the package's dependencies.

 I love it!

 However, it doesn't work AFAICS...

 Since we add to _DEPENDENCIES here, _DEPENDENCIES is not empty, and the ?= in
inner-generic-package does not trigger. That was the original reason why the
rule had to be repeated in each infra, not because we want to exclude additional
dependencies.

 So instead, what we need is a real $(2)_INFRA_EXTRA_DEPENDENCIES, which we can
safely append to because it will not be used by the package.mk file itself. Or
as mentioned on IRC, as an extra argument.

 Regards,
 Arnout
