Fix warning in stdio-common/tst-printf-round.c.

This patch fixes warnings of the form "tst-printf-round.c:202:17:
warning: passing argument 3 of 'test_hex_in_one_mode' discards 'const'
qualifier from pointer target type", by adding an extra const to that
argument (so that after array-to-pointer conversion it's const char
*const *).

Tested for x86_64.

	* stdio-common/tst-printf-round.c (test_hex_in_one_mode): Make
	third argument const.
