[PATCH] maint: release no longer creates a diff file

[Eric Blake]

Ever since commit f1cf390 (1.4.14 release), we no longer create
diff files as part of the release process.  These days, it is
assumed that it is easier to download a fresh tarball rather
than to try and use a diff file to patch an older tarball.

[The astute list reader will probably guess that I'm trying to release
1.4.18 before 2017 :) ]
