BUGID#_1083 - documentation/yocto-project-qs/yocto-project-qs.xml: Added -k option

BUGID#_1083 - I added the -k option as part of the bitbake command in the
example that builds an image.  I did not explain it as that is beyond
the scope of the quickstart.  I did however point the user to where
they can find information on it.
