[PATCH] Add warning `init=' to init/main.c

I passed init=/mylinuxrc to the kernel on the command line. The kernel silently dropped down to exec /sbin/init. It turned out that /mylinuxrc had improper permissions. Without any warning message from the kernel that something was wrong it took awhile to find the issue. The patch below adds a warning.
