Provide more space for card holder name in CAC token label
Provide more space for card holder name in CAC token label

The PKCS#15 emulation layer for the CAC uses a single PIN. Set its
label to "PIN" (rather than the card type "CAC I" or "CAC II"), so
that the PIN label will be omitted from the token label, providing
more space for the card holder name instead.

This follows the behavior used for PIV cards, which was introduced
in commit 56c8f59b25c222cfe2b57dcf78c8bbc26eb595df.
