[PATCH] When appropriate, replace the waitpid calls with wait in sbin/init/init.c

[rhl120]

Hello, while browsing the source code of init, I found a couple of calls to 
waitpid which, I believe, could be replaced with wait(NULL). As far as I can 
tell lib/libc/gen/wait.c and lib/libc/gen/waitpid.c backup my belief but on the 
other hand I am very new to this stuff so I may be wrong so sorry if this is a 
waste of your time. The FAQ says that I should send the patch inline but the 
mailing lists page says that I can send it as an attachment so I did both.
Thanks for checking out my commit!
Here is the patch:
