ntpd section isn't shown in LuCI as there is no /usr/sbin/ntpd

I'm not quite sure what we would like to achieve with https://gitlab.labs.nic.cz/turris/turris-build/blob/master/patches/openwrt/hack/0003-busybox-Try-to-install-everything-into-s-bin.patch as there is no commit message.

Unfortunately, with that patch we diverged a little bit from OpenWrt and LuCI doesn't count with that. In LuCI, there is a hard-coded path, which is looking for /usr/sbin/ntpd , if it's not there then it doesn't show ntpd section, but we have it in /sbin/ntpd. That's why I need to add /sbin/ntpd to LuCI and LuCI seems to be happy about it as it works.

This is an issue across all our Turris OS releases.
