Azure: Update some job breakdowns so we build the world again

As part of commit 9aeac898 ("Azure: Rework build the world jobs") I
made a few mistakes. An errant '_' meant that we built neither at91 nor
kirkwood platforms. Further, the non-freescale (NXP) "LS1xxx" platforms
were also not being built. Adjust some jobs to have these be built
again.
