BLFS: scriptlets should not generate a linefeed for <userinput>

[Pierre Labastie]

Recently, the dbus commands have been changed to include the following:

meson setup --prefix=/usr          \
            --buildtype=release    \
            --wrap-mode=nofallback \</userinput><userinput revision='sysv'>
            -D systemd=disabled    \</userinput><userinput>
            .. &amp;&amp;
ninja</userinput></screen>

This breaks ablfs, because the xsl (wrongly) generates a linefeed before each <userinput> tag.

Note that generating a linefeed between each block of commands is necessary, because otherwise the following xml:

<screen><userinput>text1</userinput></screen>
<para>
  blah
</para>
<screen><userinput>text2</userinput></screen>

would generate:

text1text2

which is not what we want.

But the linefeed should be added before each <screen>, not before each <userinput>
