scd: Fix flushing of CA-FPR data objects

Browse Source 
* scd/app-openpgp.c (do_setattr): Add new table item to flush a
different tag.

--

For whatever reasons the OpenPGP card reads the 3 CA fingerprints from
one object but sets them individually using 3 different tags.  The
cache flushing was not prepared for this and so a changed CA
fingerprint showed only up after a card reset.  This patch fixes it.

Signed-off-by: Werner Koch <wk@gnupg.org>
(cherry picked from commit c9f4c1f0de06672c6ae2b793d86cc001d131f9a6)

Fixed conflict by removing the UIF-* entries from the table.
