  -----------
  [lldb] Reject a zero child offset in the Mach-O export trie (#203055)

A child node offset of 0 points back at the root. ParseTrieEntries
silently skipped such a child because of a leftover guard from before
the walk tracked visited nodes, letting a malformed trie parse as valid.

Drop the guard so the visited-node set rejects it as the cycle it is,
matching how LLVM's MachO export-trie reader treats a child pointing at
an already-visited node.
