If you run 'make deb-pkg', all objects are lost due to 'make clean',
which makes the incremental builds impossible.
Instead of cleaning, pass the exclude list to tar's --exclude-from
option.
Previously, *.diff.gz contained some check-in files such as
.clang-format, .cocciconfig.
With this commit, *.diff.gz will only contain the .config and debian/.
The other source files will go into the .orig tarball.
linux.tar.gz is rebuilt only when the source files that would go into
the tarball are changed.

Changes in v6:
- Add more stubs to cmd_tar so I can reuse it for the other rules
Changes in v5:
- Avoid unneeded rebuild of the tarball when nothing in the source tree
is changed.
Changes in v4:
- Fix a typo in comment
Changes in v3:
- Add --extra-pattern='*.rej'
- Exclude symlinks at the toplevel
- Add --sort=name tar option
