core/pkg-generic: allow packages to exclude files when extracting
Currently, packages that need to exclude parts of the archives when
extracting (e.g. to gain space), like gcc or toolchain-external, have to
provide custom extract commands, just for the sake of adding a bunch of
--exclude directives when calling tar.
Add a new variable that packages may set, to provide a space-separated
list of patterns to exclude.
