gpg: Fix AEAD preference list overflow 

* g10/getkey.c (fixup_uidnode): Increase size of prefs array.
--

GnuPG-bug-id: 5050
Fixes-commit: ab7a0b0702
which introduced a feature to show the AEAD preferences of keys
created with rfc4880bis capable software (e.g. GnuPG 2.3-beta).
The same code in 2.3 is correct, though.
