These patches make it possible to use gnome-boxes, at least for the
simple virtual machine I tried to run.

Previously, I was stuck with the following error:

  Unable to start domain: unsupported configuration: this QEMU binary
  lacks smartcard passthrough mode support

  gnu: Add softhsm.
  gnu: Add libcacard.
  gnu: qemu: Add libcacard as an input to enable smartcard support.
  gnu: spice: Add libcacard as an input to enable smartcard support.
