List actual Debian/Ubuntu packages needed  

The list is updated to refer to packages which need to be installed on a system which has never used Lua.
Modified luarocks line because at least on Ubuntu the given `apt-get` command is enough to get `sile` to compile. 
Fixes “serious” > “series” error BTW.
