[Buildroot] [PATCH 0/2] package/systemd: unify journal remote options

[Michael Nosthoff]

this patch is the result of the discussion at [0] and fixes #12301.

I moved the libqrencode dependency in the first patch for two reasons:
 - it untangles the if-else construct for the remote part
 - in systemd 247 homectl will also be using libqrencode for recovery-keys [1]

In the second patch I deprecated the systemd-journal-gatewayd options as it is
now part of the systemd-journal-remote option. Also since the patch mentioned
in the discussion you already needed to set the latter to get gatewayd built.

[Buildroot] [PATCH 1/2] package/systemd: link libqrencode independent of remote

[Michael Nosthoff]

systemds libqrencode support is independent from journal-gatewayd.
In v247 it will additionally be used in homectl for recovery key
generation.

[Buildroot] [PATCH 2/2] package/systemd: group all journal-remote tools

[Michael Nosthoff]

The -Dremote=true flag enables three tools.
systemd-journal-gatewayd, systemd-journal-remote and
systemd-journal-upload.

It is not possible with simple means to install them seperately. So use
the systemd-journal-remote option do enable or disable them all together.

Drop systemd-journal-gatewayd option and add it to legacy.

Fixes: #12301
