Fix smartcard certificate removal and update

This patch fixes bug found in opensc 0.14.0-2 (Debian 8) that blocks
certificate update and removal on Athena ASEPCOS smartcard with error

    Failed to update certificate: Security status not satisfied

OpenSC tries to get the parent's 'DELETE' access before cert removal
and leaves path variable pointing to dir not file to be removed.
