init: /dev can be noexec and /run nodev

Topi Miettinen requested to merge topimiettinen-guest/initramfs-tools:fix-dev-and-run-mount-flags into master

/dev used to be mounted with "exec" flag due to /dev/MAKEDEV script but that's history and it's now located in /sbin. mmap() with file descriptor to "/dev/zero" (instead of modern mmap(,,,MAP_ANON...)) will still work.

There's no reason to have (char/block) device nodes in /run, so let's mount it with "nodev". This does not affect sockets, fifos etc.
