goinstall: process dependencies for package main
Currently to install a command, you have to manually goinstall each of the remote packages that it depends on. This patch lets goinstall P work where P is contains files in package main. It does not actually build the package, but it installs all of its dependencies and prints a message to that effect. R=rsc CC=golang-dev https://golang.org/cl/1301043
