[Stable-8.2.3 12/87] make-release: switch to .xz format by default

[Michael Tokarev]

For a long time, we provide two compression formats in the
download area, .bz2 and .xz.  There's absolutely no reason
to provide two in parallel, .xz compresses better, and all
the links we use points to .xz.  Downstream distributions
mostly use .xz too.

For the release maintenance providing two formats is definitely
extra burden too.
