bitbake: continue on failure

Add '-k' option to bitbake invocations to get Jenkins builds to continue
after falure as much as possible.  This gives us a greater view of
everything that is broken rather than just the first bitbake task which
encountered a problem, hopefully allowing more problems to be fixed at
once.
