server: Change to register signal handler with glib

server: Change to register signal handler with glib

Using std signal handler can make deadlock in terminating progress.
When std signal handler is called dispatching g_main_context,
glib attempts to lock g_main_context again.
To prevent this situation, it is needed to use glib signal handler function.

When there is a deadlock, the callstack is with below.
