[Buildroot] [PATCHv3 07/18] pkg-generic: implement source-check targets

[Thomas Petazzoni]

This commits extends the common package infrastructure with the
$(1)-source-check and $(1)-all-source-check targets.

The $(1)-source-check target simply calls the newly added
SOURCE_CHECK macro on all items to be downloaded.

The $(1)-all-source-check target will depend on the
$(1)-all-source-check targets of all dependent packages and the
$(1)-source-check target of the current package, which allows to do a
recursive source-check in the dependency tree.
