cmd/heapview: look for tools repository in all GOPATH entries

It is legal for Go packages to be in any of those places, not only
the first entry. Look in all places for golang.org/x/tools repository.
Cache the directory that is found. It's slightly more expensive
to look for it, since potentially multiple directories must be
checked for existence.
