[Buildroot] [PATCH 08/30] jpeg: convert to a real package

jpeg is a virtual package, but since it is listed in the dependencies
of other packages, it should obey to all the normal make rules for
packages. Notably, the jpeg-show-depends target is mandatory for the
graph-depends script to work.
Instead to implement such a make target manually, make jpeg a normal
generic-package, except that it doesn't have any source.
