We need /dev/ptmx -> /dev/pts/ptmx (for devpts -o newinstance)
Other way to do this thing is via bind mount (as said kernel doc[devpts.txt]).
This should be done in this way at least for /dev as devtmpfs in the chroot.
Since we can not touch /dev (devtmpfs), because devtmpfs is "singleton",
just use bind method and avoid interference.
Do it the same for both modes of /dev (tmpfs) and (devtmpfs) to keep it simple.
Currently devpts in chroot is not working without this when using /dev as devtmpfs,
this fixes this issue (opening /dev/ptmx, creates devices nodes on outside /dev/pts)
