condition, man: Add support for ConditionSecurity=smack

According to Documentation/security/Smack.txt:
  In keeping with the intent of Smack, configuration data is minimal
  and not strictly required. The most important configuration step is
  mounting the smackfs pseudo filesystem.
This means that checking the mount point should be enough.
