fix warnings on x32

[Bruno Haible]

When compiling to x86_64 with x32 ABI (the most comfortable way is on
Ubuntu 16.04 with the 'libc6-dev-x32' package), I get warnings:

test-times.c: In function ‘main’:
test-times.c:64:15: warning: format ‘%ld’ expects argument of type ‘long int’, 
but argument 2 has type ‘clock_t {aka long long int}’ [-Wformat=]
       printf ("tms.tms_utime %ldms\n", ((long int) tms.tms_utime * 1000) / 
clk_tck);
               ^

               ^

This fixes them.

        times test: Avoid gcc warnings on Linux/x32.
        * tests/test-times.c (main): Really cast printf arguments from clock_t
        to 'long int'.
