ref-manual: Updated the RDEPENDS variable to include syntax
Fixes [YOCTO #4987] This variable supports some boolean operators that we are not showing for supporting versioned dependencies. I added the explanation for them. There will be other variables affected later once we settle on the changes here.

4136 BitBake, which the OpenEmbedded build system uses, supports
4137 specifying versioned dependencies.
4138 Although the syntax varies depending on the packaging
4139 format, BitBake hides these differences from you.
4140 Here is the general syntax to specify versions with
4141 the <filename>RDEPENDS</filename> variable:
4142 <literallayout class='monospaced'>
4143 RDEPENDS_${PN} = "&lt;package&gt; (&lt;operator&gt; &lt;version&gt;)"
4144 </literallayout>
4145 For <filename>operator</filename>, you can specify the
4146 following:
4147 <literallayout class='monospaced'>
4148 =
4149 &lt;
4150 &gt;
4151 &lt;=
4152 &gt;=
4153 </literallayout>
4154 For example, the following sets up a dependency on version
4155 1.2 or greater of the package <filename>foo</filename>:
4156 <literallayout class='monospaced'>
4157 RDEPENDS_${PN} = "foo (>= 1.2)"
4158 </literallayout>
4159 </para>
