pcsc-lite: clean recipe

we get the following log at boot :
Configuring pcsc-lite.
update-rc.d: /etc/init.d/pcscd: file does not exist

as the init script is no more nedded (autoload feature
of the daemon by the clients), we can remove the previously
unused init script and clean the recipe in order not
to have any update-rc interaction.
