Zbigniew Jędrzejewski-Szmek fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

<title>Description</title>
<para><function>sd_machine_get_class()</function> may be used to
determine the class of a locally running virtual machine or
container that is registered with
<citerefentry><refentrytitle>systemd-machined.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
The string returned is either <literal>vm</literal> or
<literal>container</literal>. The returned string needs to be
freed with the libc <citerefentry
project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
call after use.</para>
<para><function>sd_machine_get_ifindices()</function> may be used
to determine the numeric indices of the network interfaces on the
host that are pointing towards the specified locally running
virtual machine or container that is registered with
<citerefentry><refentrytitle>systemd-machined.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
The returned array needs to be freed with the libc <citerefentry
project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>
call after use.</para>

<title>Return Value</title>
<para>On success, these calls return 0 or a positive integer. On
failure, these calls return a negative errno-style error
code.</para>

<title>Errors</title>
