MAKEDEV: Set default perms on /dev/lua to 0600.

Otherwise unprivileged users can submit Lua code into the kernel, if
lua.kmod is loaded (which doesn't happen by default, not even
autoloaded on demand).

lua(4): Fix and test some issues.

- Require read permission for LUAINFO.
- Require write permission for all others:
  . LUACREATE
  . LUADESTROY
  . LUALOAD
  . LUAREQUIRE
- Don't panic in LUAINFO if there's zero states.
- Add missing sys/stdbool.h in sys/lua.h.

This is not a real test suite for lua.kmod -- it doesn't verify the
module does anything useful; it just verifies that _if_ you go out of
your way to load the experimental kernel module, it doesn't enable
unprivileged users to wreak havoc with /dev/lua.
