Subject: [PATCH] scripts/package/Makefile: put proper config in source tarball

It is widely known that one can build a kernel without a .config in the
source tree by setting KCONFIG_CONFIG equal to the actual configuration
file path.

When making a *-pkg target, make(1) prepares a source tarball and tries
to pack `.config' in there regardless of the value of KCONFIG_CONFIG,
failing spectacularly if .config is absent and packing the wrong config
if it exists.
Let's fix that.
