ref-manual: update PACKAGECONFIG glossary entry
Update the glossary entry for PACKAGECONFIG in two ways: 1) Explain the recent sixth argument, which identifies conflicting features for a given feature. 2) Use a different example, as the librsvg "croco" feature no longer works that way. (From yocto-docs rev: af9bf61a54c059e72c807ca8061a57d6fe74c5fa) Signed-off-by: Robert P. J. Day <rpjday@crashcourse.ca> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
