[Pcsclite-muscle] socket activation

[Nikos Mavrogiannopoulos]

Hi,
 It was reported in fedora bz [0] that an application would trigger
pcsc-lite server to start (we use systemd socket activation). 

The application seems to call `SC(EstablishContext, SCARD_SCOPE_USER,
nullptr, nullptr, &d->context);` in order to detect a running pcscd and
fails when pcscd is not yet activated. Is that the expected way to
detect pcscd running?

regards,
Nikos
