Do not print 'dangling' for cat-file in case of ambiguity

The return values -1 and -2 from get_oid could mean two different
things, depending on whether they were from an enum returned by
get_tree_entry_follow_symlinks, or from a different code path.  This
caused 'dangling' to be printed from a git cat-file in the case of an
ambiguous (-2) result.

Unify the results of get_oid* and get_tree_entry_follow_symlinks to be
one common type, with unambiguous values.
