This also enables the "list" subcommand of xkbcli.
Since libxkbregistry is an optional library we could install it into a
different output. However, doing this properly is quite challenging and
the best approach would likely be to upstream patches that add a Meson
option for installing libxkbregistry under a separate prefix (so that
the pkg-config file is generated correctly, etc.).
But even then the default fixup phase would try to move
$libxkbregistry/include into the $dev output and the $out output would
depend on the $libxkbcommon output because of the xkbcli binary (though
we could move that into a $bin output).
As a result it seems best not to install libxkbregistry into a dedicated
output path.
Relevant changes:
- Add libxml2 as a required dependency
- Disable libxkbregistry for now (a new but optional library -> install
into a dedicated output when we need it)
- Set the lookup path for system data files to /etc/xkb
- Enable the tests
- Extend the meta attributes and minor code style changes

Fixes build of i3lock and to possibly prevent breakage of other
packages, I've tested building of gtk3 and qt5 (partial, core2duo here).
I know it's not a comprehensive test but we can still revert in case
Hydra reports more builds failing.
