shared: Replace syscommon_proc_is_app() with security-manager API

Instead of syscommon_proc_is_app() which had been accessing smack node
'/proc/<pid>/attr/current' directly, use security-manager API instead.
It is especially important where smack is not support. The
security-manager API can handle such case in contrast to accessing
the smack node directly.
