    cert-chooser-button: forward mnemonic_activate to the button implementation
    
    This makes the NMACertChooserButton respond to mnemonic-activate signal
    by forwarding it to the either PKCS#11 or file chooser button, depending
    on which is actually used.
    
    Fixes: 727282cc8c87 ('cert-chooser-button: rework, making GCK dependency optional')
