Use Debian specific config files

Use /etc/default/keyboard instead of /etc/X11/xorg.conf.d/00-keyboard.conf for
keyboard configuration.

Read/write /etc/timezone if /etc/localtime does not exist.

test: enable systemd-oomd.service

Enable the service to ensure dbus-org.freedesktop.oom1.service exists
and D-Bus activation works.

See #18469

units: don't install dbus-org.freedesktop.oom1.service alias

The systemd-oomd.service unit contains

[Install]
WantedBy=multi-user.target
Alias=dbus-org.freedesktop.oom1.service

which means the symlink is supposed to be created dynamically when the
service is enabled.

test: explicitly configure oomd stuff via dropins

so we don't get overridden by distro-shipped ones.

oomd: move oomctl to bindir

We don't really need oomctl during early boot, so bindir seems like a
more suitable place for the binary.
