gpg: accept subkeys with a good revocation but no self-sig during import

* g10/import.c (chk_self_sigs): Set the NODE_GOOD_SELFSIG flag when we
encounter a valid revocation signature. This allows import of subkey
revocation signatures, even in the absence of a corresponding subkey
binding signature.

This fixes the remaining test in import-incomplete.scm.
