Add libprivilege-control tests for NOSMACK environment.

Add libprivilege-control tests for NOSMACK environment.

[Issue#]        SSDWSSP-417
[Feature]       Add new libsprivilege-control tests that test libprivilege-control behaviour on
                NOSMACK environment. Remove stub test cases used to test macros for different
                testing environments.
[Cause]         When previous tests were launched on NOSMACK environment they returned false errors
                because the system behaved differently with SMACK turned off.
[Solution]      Creating new tests that would expect different behaviour from libprivilege-control.
[Verification]  After successful compilation launch libprivilege-control tests on NOSMACK env.
                Tests that previously failed and were turned off in one of my previous commits
                should appear with "_nosmack" ending in name.
