init.d/vz-gentoo: don't call tools by absolute path
Apparently in recent Gentoo the ip tool was moved from /sbin to /bin,
so this initscript stopped working.
Apparently runscript makes sure all the needed directories are in PATH
(I have tested with runscript from baselayout-126.96.36.199, pretty old one)
so we can just drop the /sbin/ prefix.
While at it, do it not only for ip, but also for modprobe and sysctl.
