abstractions: Do not allow ld.so.preload by default in abstractions/base
This entry has security implications and it should NOT have ever been allowed by default in abstractions/base. This reverts commit 36244d48 ("add ld.so.preload to <abstractions/base>")
Note: while most systems are currently setup this way, access to /etc/ld.so.preload does not mean a user is actually capable of policy admin.
Nominated for every release this rule made its way into
