libcgroup: Fix compile warning in cgrulesengd.c

We were getting a warning while compiling on 64 bit platforms,

[root@llm72 trunk]# make
cc -std=gnu99 -DDEBUG -g -O2 -I. -DPACKAGE_VERSION=0.32 -Wall -o cgrulesengd cgrulesengd.c \
                -L . -lcgroup -lpthread
cgrulesengd.c: In function ‘cgre_create_netlink_socket_process_msg’:
cgrulesengd.c:327: warning: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long unsigned int’

According to Dan Smith, its just an overzealous format check and so
we just cast the size to integer and print it.
