glib-2.0: Ignore useless warning found with gcc-6

../../glib-2.46.2/glib/gdate.c:2497:7: error: format not a string literal, format string not checked [-Werror=format-nonliteral]
       tmplen = strftime (tmpbuf, tmpbufsize, locale_format, &tm);
       ^~~~~~

| ../../../../../../../../workspace/sources/glib-2.0/glib/tests/gdatetime.c: In function 'test_strftime':
| ../../../../../../../../workspace/sources/glib-2.0/glib/tests/gdatetime.c:1338:3: error: '%c' yields only last 2 digits of year in some locales [-Werror=format-y2k]
|    "a%a A%A b%b B%B c%c C%C d%d e%e F%F g%g G%G h%h H%H I%I j%j m%m M%M " \

Additionally fix the problem seen where write() return code is ignored
