riscv: Bump COMMAND_LINE_SIZE value to 1024

Browse Source 
Increase COMMAND_LINE_SIZE as the current default value is too low
for syzbot kernel command line.

There has been considerable discussion on this patch that has led to a
larger patch set removing COMMAND_LINE_SIZE from the uapi headers on all
ports.  That's not quite done yet, but it's gotten far enough we're
confident this is not a uABI change so this is safe.
