[pkgselectprocess] Fix usage of checkpackage-backend

Browse Source 
If checkpackage-backend does not exist in the target system, likely due to the
use of stacked squashfses, ensure it temporarily exists so it can be used in
the install process. This fixes installation of the Virtual Machine Manager
when selected on the Customize menu (LP: #2104243).
