Following warning is encountered when building selftests on powerpc/32.
CC csum
csum.c: In function 'recv_get_packet_csum_status':
csum.c:710:50: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'size_t' {aka 'unsigned int'} [-Wformat=]

csum.c:710:63: warning: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'unsigned int' [-Wformat=]

cm->cmsg_len has type __kernel_size_t and CMSG() macro has the type
returned by sizeof() which is size_t.
size_t is 'unsigned int' on some platforms and 'unsigned long' on
other ones so use %zu instead of %lu.
