cryptopensc support for usb readers broken

[Magosányi Árpád]

1. The cryptopensc hook misses to copy over some files to initramfs. It is probably due to the fact that it blindly copies /usr/lib/pcsc, missing some library dependencies and a file symlinked there.
In case of libccid the hook at the end of report adds the needed files as a workaround.
2. Also stopping the pcsc daemon does not work (for a long time, probably since maverick):
- it tries to use start-stop-daemon, which is not in the initramfs
- it looks at /sbin for pcscd and it is now in /usr/sbin
As a workaround, the init script at the end of the report works
3. I'm not sure of this/etc/initramfs-tools/hooks/straceu one, but it seems that the cryptopensc script does not ask the password using plymouth. I could use it only by pressing Esc in the boot screen. Maybe I was the impatient one.
