Remove After=local-fs.target from containerd.service

As we are not setting `DefaultDependencies=no`, containerd.service
'will have dependencies of type Requires= and After= on sysinit.target'
https://www.freedesktop.org/software/systemd/man/latest/systemd.service.html#Default%20Dependencies
and sysinit.target already has After=local-fs.target
https://www.freedesktop.org/software/systemd/man/latest/bootup.html#System%20Manager%20Bootup
