[Buildroot] [PATCH 1/4] legal-info: extract even no-redistribute packages

[Yann E. MORIN]

From: "Yann E. MORIN" <yann.morin.1998 at free.fr>

Currently, if a package is marked _REDISTRIBUTE = NO, then legal-info
will not try to extract it first.

If that package also declares some _LICENSE_FILES, legal-info fails
if it is the only action we're trying to run:

    $ cat defconfig
    BR2_arm=y
    BR2_TOOLCHAIN_BUILDROOT_EGLIBC=y
    BR2_PACKAGE_LIBFSLCODEC=y
    $ make BR2_DEFCONFIG=$(pwd)/defconfig defconfig
    $ make legal-info
    [--SNIP--]
    cat: /home/ymorin/dev/buildroot/O/build/libfslcodec-3.5.7-1.0.0/EULA: No such file or directory

Fix this by always having legal-info extract the archives if one or
more _LICENSE_FILES are specified.

We do this for all types of packages: overridden, local or 'normal'
remote packages. Even though we do not save the sources for the
overridden or local packages, we need to save their licensing info,
so we need to extract them.

This implies that we now need only PKG-source, not PKG-extract anymore,
as a dependency of legal-info for packages we want to save (ie.
redistributable, non-local and non-overriden packages.)

Chamges v5 -> v6:
  - fix commit log about the actual case that is being solved  (Luca)
  - fix the comment about needing only PKG-source  (Luca)

Changes v4 -> v5:
  - my usual s/pacakge/package/

Changes v3 -> v4:
  - legal-info needs to depend on PKG-source when it needs to save a
    package's tarball

Changes v2 -> v3:
  - don't include source URL of no-redistribute, or overriden, or local
    packages in the manifest

Changes v1 -> v2:
  - this is not fixing the autobuilders failure it was written to fix,
    so remove the references to such build failures  (Thomas P)
  - also extract overriden and local packages  (Fabio)
