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.
