Drop the fgci_socket keyword and move "listen on" into the per-server context.

A valid config now looks like this:

[[[
prefork 1

server "localhost-unix" {
	repos_path "/got/public"
	unix_socket_name "/run/gotweb.sock"
}

server "localhost-tcp" {
	repos_path "/got/public"
	unix_socket		off
	listen on 127.0.0.1
	port 9000
}
]]]

ok?

My end goal is to allow a server instance to listen on multiple ports
and/or addresses, like this:

server "default" {
	unix_socket_name "/run/gotweb.sock"
	listen on 127.0.0.1 port 9000
	listen on ::1 port 9000
	listen on 192.168.1.1 port 9001
}

More changes will be needed to achieve this, but getting rid of the
"fcgi_socket" keyword is an important step.
