[PATCH i-g-t] overlay: Fix compiler warning when compiling with meson

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

[1/316] Compiling C object 'overlay/intel-gpu-overlay@exe/overlay.c.o'.
../overlay/overlay.c: In function ‘show_gem_objects’:

Might as well give it the 309 bytes it wants, plus on more. :-)
