[llvm] Fix MachO exports trie parsing.

The exports trie parser ordinal validation check doesn't consider the case where
the ordinal can be zero or negative for certain special values that are defined
in BindSpecialDylib. Update the validation to account for that fact and add a
test case.

This fixes rdar://94844233.
