iproute2: fix build failure on sparc due to -Wformat and tv_usec

tv_usec is "suseconds_t" which is apparently usually
a signed long, but sometimes not....
Change the printf modifier to use signed and
cast the tv_usec to long in case it's not already long.

utils.c: In function 'print_timestamp':
utils.c:802:2: error: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type '__suseconds_t' [-Werror=format]
cc1: all warnings being treated as errors
