rpm builds: Fix warnings and output

There are several groups of warnings and output that should be fixed in
the kernel's rpm build commands.

1. The output of pathfix.py is too noisy. Users do not need to see the
   directory traversal messages, and only need to see files that were changed
   (or not changed) by the script.

2. There is a vmlinux_decompressor error in !s390x builds. This code
   must only be executed on s390x builds.

3. There are references to an old .tmp_versions directory that is no
   longer used in the build. These references can be removed entirely from
   the tree.

4. There are "File listed twice" rpm build errors that occur because the
   rpm spec's kernel-modules-internal section %files section lists them
   twice. Of course, they should only be listed once.

The four commits in this series fix the above four issues.
