Vincent Breitmoser 7cc68a961d gnupg: apply patch to allow import of key updates without user ids
This adds a patch series which allows GnuPG to import updates
(revocations and subkeys) from certificates that contain no user ids.
This is relevant for refreshing keys from the default keyserver
keys.openpgp.org, where only user ids that contain verified email
addresses will be distributed, and revoked keys never contain any user
ids.

This patch series was originally authored and submitted to upstream half
a year ago (by me), but now comes from Debian packaging where it's been
included since then.

Relates to the following upstream issue: https://dev.gnupg.org/T4393

Subject: 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.
