documentation/poky-ref-manual/ref-variables.xml: updated RDEPENDS 

Per Paul Eggleton's suggestion I updated the description of this
variable.  Some minor wording changes as well as covering two
automatic handling features.

(From yocto-docs rev: 15be3502ca20f657051e02d698b459328328fb14)

This enables the package to run correctly.
For example, consider a Perl script, which depends on the Perl package.
Since this variable applies to
output packages, there would usually be an override attached
to this variable such as <filename>RDEPENDS_${PN}-dev</filename>.
output packages, there should always be an override attached
to this variable specifying the runtime package to which to add the
dependency (e.g. <filename>RDEPENDS_${PN}-dev</filename>).
Names in this field must appear as they appear in the
<filename><link linkend='var-PACKAGES'>PACKAGES</link></filename> namespace before any
renaming of the output package by classes like <filename>debian.bbclass</filename>.
