[klibc] run-init: get rid of over paranoid test for /init
switch_root in util-linux hasn't it either.
cc0c0262 added the checks, but probably didn't have the following
application in mind.
In fact it can break chainloading of bigger initramfs out of small one:
"I boot via pxe, kernel + very small ramfs this ramfs start an
application that grabs a bigger ramfs and store it locally
I did the following: creating a tmpfs, uncpio the ramfs and try to
run-init on it, but my miniramfs doesn't have a /init as I specified
rdinit=/sbin/init."
So for now just get rid of that check.
