Refactor perm_app_setup_path libprivilege-control tests.

Refactor perm_app_setup_path libprivilege-control tests.

New design provides only three ways of labelling path in libprivilege-control.
See:
-> 'Added APP_PATH_PUBLIC and APP_PATH_FLOOR types to perm_app_setup_path function.'

Verification:
-> libprivilege-control-test --output=text --runignored
   (following tests should pass:
    -> privilege_control02_perm_app_setup_path_01_PRIVATE
    -> privilege_control02_perm_app_setup_path_02_FLOOR
    -> privilege_control02_perm_app_setup_path_03_PUBLIC_RO
    -> privilege_control02_perm_app_setup_path_03_PUBLIC_RO_nosmack)
