CI: Add Valgrind suppression support Add an empty Valgrind suppressions file, use it when invoking Valgrind. This prepares for addition of Valgrind suppressions for current false positives and issues that cannot be fixed, preparing for enforcing Valgrind check.

This simplifies discovery and addition of new suppressions and removal of unused ones. Related to https://fedorahosted.org/sssd/ticket/2428 Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
