tests: avoid awk+printf+\xHH portability trap

* tests/init.cfg (hex_printf_): Rewrite in terms of printf and sed.
Using awk's printf with \xHH in the format string was not portable
to the awk of Solaris 10, AIX 7 or HP-UX 11.23, as reported in
http://debbugs.gnu.org/18987.
* tests/word-multibyte: Use printf rather than hex_printf_,
and give the character we're printing a name: e_acute (rather
than A-grave), since that is used in other tests.
a trailing \n in the format string, adjust by removing it, and
instead invoking echo.
* tests/multibyte-white-space: Simply remove each trailing \n.
They were not needed.
