libctf: do not crash when CTF symbol or variable linking fails
When linking fails, we delete all the generated outputs, but we fail to
remove them from the ctf_link_outputs hash we stuck them in before doing
symbol and variable section linking (which we had to do because that's
where ctf_create_per_cu, used by both, looks for them). This leaves
stale pointers to freed memory behind, and crashes soon follow.
Fix obvious.

* ctf-link.c (ctf_link_deduplicating): Clean up the ctf_link_outputs
hash on error.
