libcamera: process: Properly ignore unused result with gcc
Casting the return value of a function to (void) doesn't ignore the
unused result warning with gcc. Use a #pragma to fix this properly, to
fix compilation with _FORTIFY_SOURCE.
Fixes: df23ab95f3d7 ("libcamera: process: fix compilation on Chromium OS")
