nixos/pcscd: Improve and clean up module
So far the module only allowed for the ccid driver, but there are a lot of other PCSC driver modules out there, so let's add an option called "plugins", which boils down to a store path that links together all the paths specified. We don't need to create stuff in /var/lib/pcsc anymore, because we patched pcsclite to allow setting PCSCLITE_HP_DROPDIR. Another new option is readerConfig, which is especially useful for non-USB readers that aren't autodetected. The systemd service now is no longer Type=forking, because we're now passing the -f (foreground) option to pcscd. Tested against a YubiKey 4, SCR335 and a REINER SCT USB reader.
