S390: Fix build error with gcc6 in utf8_utf16-z9.c.
This patch fixes the build error with gcc6:
array subscript is above array bounds [-Werror=array-bounds]
While including loop.c to construct the SINGLE(LOOPFCT) method
for converting from UTF-16 to UTF-8, the bytebuf array with length
MAX_NEEDED_INPUT is used as inptr. MAX_NEEDED_INPUT defaults to
MIN_NEEDED_INPUT if not defined before including loop.c.
Thus bytebuf has a length of 2.
This patch defines MAX_NEEDED_INPUT to MAX_NEEDED_TO, which is 4.
ChangeLog:
* sysdeps/s390/s390-64/utf8-utf16-z9.c
(MAX_NEEDED_INPUT): New define.
(MAX_NEEDED_OUTPUT): New define.
