Yann E. MORIN fcf465d04b utils/checkpackagelib: add check for CPE variables set to default values
Now that we can specify that the default values for the CPE_ID variables
are valid, without having to actually set one (or more) to their
default, add a check-package check that validates that the CPE_ID
variables are indeed not set to their default.

It also validates that CPE_ID_VALID is not set when another CPE_ID
variable is set to a non-default value.

Add an anchor in the manual so that we can easily point to it.
