tracepath: Fix print time_t problem on 32 bits musl

Similarly to 0fd2db7 this fixes warning on 32 bit musl 1.2.0, which
changed time_t as 64-bit across all archs [1]. This fixes warning:

../tracepath.c:287:26: warning: format '%ld' expects argument of type
'long int', but argument 2 has type 'time_t' {aka 'long long int'} [-Wformat=]
  287 |   printf(_("%3ld.%03ldms "), res.tv_sec * 1000 + res.tv_nsec / 1000000,
