- pins component/fluentd gems version to fix :

  ERROR:  Error installing fluentd:
	msgpack requires Ruby version >= 2.4.

  encountered while supplying software/fluentd in a SlapOS Webrunner.

- removes outdated gem arguments '--no-ri --no-rdoc'
  by default `rubygemsrecipe` uses '--no-document' (see https://lab.nexedi.com/nexedi/rubygemsrecipe/blob/master/rubygems.py#L206)

- splits `gem-options` arguments to fit the README example (see https://lab.nexedi.com/nexedi/rubygemsrecipe/blob/master/README.rst#L50)

- adds minimal test to check fluentd SR instanciation

The keyboard option is actually not recommended in the QEMU
documentation
(https://manpages.debian.org/buster/qemu-system-x86/qemu-system-x86_64.1.en.html).
After some tests, it appears that noVNC is already sending raw keyCode
to QEMU since 2016 (see
https://github.com/novnc/noVNC/commit/f4f4e8993d6daeb43b957766cd6973993232ba13).

More information can be found in

rotate_size 0 or rotate_size -1 does not help to disable rotation, so
workaround it by setting very big rotation limit.

It was formatted with a '\t', which json-schemas test does not allow.

We are not using this

This host header is not passed by default, because we are already using
proxy_set_header, so we need to set it explicitly.

It seems that since we updated some packages in in 279486fe (stack/slapos:
version up some eggs with known vulnerabilties, 2021-01-28) slaprunner was
producing URLs with "localhost" as hostname when using redirect(url_for(...))

As discussed in https://github.com/nextcloud/news/issues/1306 a new release was
uploaded.

Commit 2f4d8cf8 fixed the following error:

  Generating phar.php
  .../parts/apache-php__compile__/php-7.3.6/sapi/cli/php: error while loading shared libraries: libzstd.so.1: cannot open shared object file: No such file or directory
  Makefile:420: recipe for target 'ext/phar/phar.php' failed

and only -rpath is needed.

apache-php does not actually depend on zstd (hence the removal of the 'extends'
line) but there's something not smart:
