base-files: set ptmxmode to 666
Make sure that the (newer) /dev/pts/ptmx is accessible by users. This
is useful e.g. when running containers which symlink /dev/ptmx to
/dev/pts/ptmx on start. The default mode (000) does not allow to
create ptys inside the container.
Using 666 when symlinking /dev/ptmx is also recommended by the kernel
documentation when /dev/ptmx is symlinked:
https://www.kernel.org/doc/Documentation/filesystems/devpts.txt
Also buildroot uses ptmxmode=0666. The patch introducing the change
explains related use cases why this is necessary a bit more in depth:
