selinux: reject duplicate symbol values during policy load

The symbol index functions assign unconditionally, so two symbols that
share a value silently overwrite each other and leave another value with
no entry.
Reject a value whose slot is already populated, for commons, classes,
roles, types, users, sensitivities and categories;
booleans already have their own "declared but not defined" check.
