inets: Remove SSI (Server Side Includes)

SSI is an old technique implemented by mod_include, that was badly
tested and not recommended to use, as having the server parse HTML
pages is a double edged sword!  It can be costly for a heavily loaded
server to perform parsing of HTML pages while sending
them. Furthermore, it can be considered a security risk to have
average users executing commands in the name of the Erlang node user.
