Subject: [PATCH] clean old chromeos-base/chromeos-bsp-null

We are converting virtual/chromeos-bsp to a new style virtual, but we
have to clean out the old one first as it has a PROVIDE= which messes
up the upgrade process.

BUG=chromium-os:38307
TEST=`./update_chroot` uninstalled this pkg for all generic boards
CQ-DEPEND=CL:42188
