This fixes a race condition where LBP1 could copy the user agent elsewhere in memory before Patchwork writes to it, thus still sending the original one to the gameserver

Looks like this mainly affected RPCS3 and not real hardware

Has this been tested on RPCS3 and PS3? If not I can give it a shot.

prx.c

					
				@ -84,11 +84,27 @@ void patch_thread(uint64_t arg) {

				    const sys_pid_t processPid = sys_process_getpid();

				    uint8_t game = 0;

				    int password_randomized = 1;

This is a nitpick, but we're targeting C99, maybe best to use stdbool here?

I tested on RPCS3 only, couldn't test on PS3 since mine broke ¯\_(ツ)_/¯
