Version: 24.3

Thanks; applied to emacs-24 branch.
It's not worth a NEWS entry, but it can have a :version bump in the
defcustom.

(I have the feeling this tarfile-extension information is being stored
in multiple places in Emacs.)

DESCRIPTION:

Old shell mode (not E-Shell, but 'M-x shell') does not recognize '.xz' as
a valid tarfile extension. This grows in annoyance as more and more
archives come in this format. This simple patch fixes the problem. The
change itself is five characters big; the rest is NEWS and ChangeLog.
