kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.package

scripts/package/Makefile does not use $(obj) or $(src) at all.
It actually generates files and directories in the top of $(objtree).
I do not see much sense in descending into scripts/package/.

+# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm

+# Process to create the rpm files
+# a) clean the kernel

+# c) Build a tar ball, using symlink to make kernel version
+#    first entry in the path
+# d) and pack the result to a tar.gz file
+# e) generate the rpm files, based on kernel.spec
+# - Use /. to avoid tar packing just the symlink
