[Buildroot] [buildroot] patch for systemd, add systemd-journal-remote

[Yann E. MORIN <yann.morin.1998@free.fr>]

Yi, All,

On 2019-06-12 08:04 +0800, Yi Zheng spake thusly:

Sending to the mailing list like you did _is_ the correct way to send
submission to add new feature to Buildroot.

Yet, here are a few comments:

Use "git send-email" to send the patch: this will send an email
properly formatted with the patch

The commit log for the patch should lokok like:

    topic: small one-line description

    A few mult-line description that explains what the patch
    does in a bit more details than the title does

    Signed-off-by: Your Real NAME <your-emal@adress>

Which in this case could translate to something like:

    package/systemd: add option to enable systemd-journal-remote

    systemd-journal-remote was added in systemd v211, so add a new option
    to enable or disable it.

    Signed-off-by: Yi Zheng <goodmenzy@gmail.com>

Be sure to run "make check-package" to catch any coding-style issues
(there are some).

Shorten the prompt to just "enable systemd-journal-remote".

Since it depends on BR2_PACKAGE_SYSTEMD_JOURNAL_GATEWAY, it should be
located after it, below.

Please also explicitly disable it when the option is not set, like all
the other options are handled (see BR2_PACKAGE_SYSTEMD_HWDB for an
example).
