Drop /usr/local/sbin:/usr/sbin from $PATH

If $PATH is not set, we get the default from crun [1]:
  PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
This is not useful, because in the image, /bin, /sbin, /usr/sbin are all
symlinks. /usr/local/sbin does not exist.

When /usr/sbin is a symlink to /usr/bin, and we use have a $PATH with
/usr/sbin before /usr/bin, various tools will discover /usr/sbin/foo when
looking for 'foo' [2], which is confusing and ugly.
