libcacard/vcard_emul_nss: handle no readers at startup

When starting with no readers, coolkey should show no slots (with
RHBZ 806038 fixed). Fix initialization to launch the event handling
thread for each module that isn't the internal module regardless of the
number of slots detected for it at initialization time, since slot
number may start as 0 and is dynamic.

RHBZ: 802435
