kmscube: Bump to latest version to fix mips64el errors

Building kmscube for mips64el leads to the following build error:

cube-tex.c: In function 'get_fd_rgba':
cube-tex.c:230:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < texh; i++) {
  ^
cube-tex.c:230:2: note: use option -std=c99 or -std=gnu99 to compile your code
cube-tex.c: In function 'get_fd_y':
cube-tex.c:261:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < texh; i++) {
  ^
cube-tex.c: In function 'get_fd_uv':
cube-tex.c:292:2: error: 'for' loop initial declarations are only allowed in C99 mode
  for (int i = 0; i < texh/2; i++) {

I have sent a fix to mainline kmscube to address such issue, so bump to
the latest version.
