configure_opensc_nss_db remediation fix

[mildas]

Description:

The remediation needs to ensure that opensc is installed because it uses the pkcs11-switch script from the package and it also needs opensc for NSS db.

/usr/bin/pkcs11-switch is the script for switching db. Not the $(/usr/bin/pkcs11-switch) output (the script outputs current NSS db - "opensc", "coolkey", or empty string).

Unfortunately, the remediation still might not work as expected on rhel7, because the database switch might require user interaction, see https://bugzilla.redhat.com/show_bug.cgi?id=1719753. It works when no database is set (no user interaction needed). However, when e.g. coolkey is used, then user is propted with:
