Remove deprecated SS_SMACK logs.

Remove deprecated SS_SMACK logs.

Each api privided by security-server uses separate socket. Each socket
is secured with diffrent smack label (for example socket:
security-server-api-data-share.sock is secured with label
security-server::api-data-share). In this way all deny logs connected
with smack were moved from dlog to dmesg. Also secure mechanism
connected with SMACK was removed from security-server code. Now,
secuirty-server is using SMACK check provided by linux kernel.
