[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.
