Nowadays the ordering of package databases is less important than it used
to be, because we have Package Ids, so shadowing is harmless and a missing
package database just causes an error. So we could treat them like a set
instead of a stack.
However, I think it's useful to prevent the user pacakge database from
depending on other external package databases - it's a reasonable sanity
check, and prevents you from installing packages in the user database that
are broken without the appropriate `-package-conf` flag.
