[FYI] {master} dist: remove support for lzma (superseded by xz and lzip)

[Stefano Lattarini]

See also commit `v1.11-611-ge637fa2' (from maint), where support
for lzma compression of distribution archive had been deprecated.

* NEWS: Update.
* lib/Automake/Options.pm: Error out if the `dist-lzma' option
is used.
* lib/am/distdir.am: Remove all support for the creation of a
lzma-compressed distribution archive.
* tests/lzma.test: Update.
