libfido2-util: show also verity features when listing FIDO2 devices (#35295)

This way, users don't have to check those features using an external
program, or wait for later failure when trying to enroll using an
unsupported feature.

E.g.:

```
# systemd-cryptenroll --fido2-device list
PATH         MANUFACTURER PRODUCT               RK  CLIENTPIN UP  UV
/dev/hidraw2 Yubico       YubiKey OTP+FIDO+CCID yes no        yes no
```
