qemu: Introduce qemuBuildSmartcardCommandLine
Add new function to manage adding the smartcard device options to the command line removing that task from the mainline qemuBuildCommandLine. Alter the logic slightly to make !nsmartcards check first so that remainder of the code is less indented. Signed-off-by: John Ferlan <jferlan@redhat.com>
