scons: Bump C standard to gnu11 on macOS 10.15.
Fix build error on macOS 10.15 Catalina.
src/util/u_queue.c:179:7: error: implicit declaration of function 'timespec_get' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
timespec_get(&ts, TIME_UTC);
^
timespec_get needs C11 starting with macOS 10.15.
