Joseph Myers be97091638 Fix nss/tst-nss-test1.c format warning.
Testing for 32-bit x86 shows up a warning "tst-nss-test1.c:25:3:
warning: format '%ju' expects argument of type 'uintmax_t', but
argument 2 has type 'int' [-Wformat=]".  The argument is a difference
of two pointers, a signed quantity of type ptrdiff_t for which the
right format is %td; this patch makes this test use that format.

Tested for 32-bit x86.

	* nss/tst-nss-test1.c (do_test): Use %td printf format for pointer
	difference, not %ju.
