[Buildroot] [PATCH 02/21 RFC] pkg-infra/pkg-generic: define PKGDIR for all rules

[Yann E. MORIN]

When we eventually support more than one br2-external tree, packages
won't be able to use $(BR2_EXTERNAL)/PACKAGE_PATH to reference files in
the package's directory (the directory with the package's .mk file).

Define PKGDIR for all our rules, so packages can simply reference it to
find their files.

This can also be used for our own packages, to avoid hard-coding the
path to our own files as well.
