[Fabrice Fontaine]

Fix the following build failure with gcc 4.8 raised since bump to
version 1.20.0 in commit f94ba5c31cf7f863e6fae996fc042a56e20118f3 and
https://gitlab.freedesktop.org/wayland/wayland/-/commit/80164ef3005e8bb5f785082b97a75cab15444f82:

../src/wayland-util.c: In function 'for_each_helper':
../src/wayland-util.c:373:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (size_t idx = 0; idx < count; idx++) {
  ^
../src/wayland-util.c:373:2: note: use option -std=c99 or -std=gnu99 to compile your code

Fixes:
