[Release][GLib] Replace c_glib/ after running c_glib/autogen.sh in dev/release/02-source.sh

[asfimport]

c_glib/ source archive is generated by make dist because includes configure script.
The current dev/release/02-source.sh build Arrow C++ and Arrow GLib to include the artifacts of GTK-Doc and then run make dist. But it is slow.
So run only c_glib/autogen.sh and then replace c_glib/.
