xorg-sgml-doctools: upgrade 1.12 -> 1.12.1

Upstream 1.12.1 adds a meson build system alongside autotools (with CI
checks comparing the installed file list against xorgproto), aligns the
meson settables with the autotools ones, refreshes the gitlab CI
templates, and drops the "All rights reserved" phrasing from the Oracle
copyright notices.  That copyright change alters COPYING, so
LIC_FILES_CHKSUM is updated accordingly (license terms themselves, MIT,
are unchanged).  Upstream also switched the release tarball compression
from bzip2 to xz, so SRC_URI_EXT is set to "xz".  The recipe continues
to build with autotools.
