cmd/gomobile: handle modules replaced by other versioned modules

Previously, gomobile bind's go.mod generation logic assumed
replacing module was always located in the disk, but is not
always true. It's valid to replace a module(version) with
another module&version.

For example,

replace golang.org/x/tools => ../

causes:

{
        "Path": "golang.org/x/tools",
        "Version": "v0.0.0-20191017151554-a3bc800455d5",
        "Replace": {
                "Path": "../",
                "Dir": "/usr/local/google/home/hakim/go/src/golang.org/x/tools",
                "GoMod": "/usr/local/google/home/hakim/go/src/golang.org/x/tools/go.mod",
                "GoVersion": "1.11"
        },
        "Dir": "/usr/local/google/home/hakim/go/src/golang.org/x/tools",
        "GoMod": "/usr/local/google/home/hakim/go/src/golang.org/x/tools/go.mod",
        "GoVersion": "1.11"
}

replace github.com/anacrolix/torrent v1.13.0 => gitlab.com/axet/torrent v0.0.0-20200205141541-92b4b9e7387e

causes:

{
        "Path": "github.com/anacrolix/torrent",
        "Version": "v1.13.0",
        "Replace": {
                "Path": "gitlab.com/axet/torrent",
                "Version": "v0.0.0-20200205141541-92b4b9e7387e",
                "Time": "2020-02-05T14:15:41Z",
                "Dir": "/usr/local/google/home/hakim/go/pkg/mod/gitlab.com/axet/torrent@v0.0.0-20200205141541-92b4b9e7387e",
                "GoMod": "/usr/local/google/home/hakim/go/pkg/mod/cache/download/gitlab.com/axet/torrent/@v/v0.0.0-20200205141541-92b4b9e7387e.mod"
        },
        "Dir": "/usr/local/google/home/hakim/go/pkg/mod/gitlab.com/axet/torrent@v0.0.0-20200205141541-92b4b9e7387e",
        "GoMod": "/usr/local/google/home/hakim/go/pkg/mod/cache/download/gitlab.com/axet/torrent/@v/v0.0.0-20200205141541-92b4b9e7387e.mod"
}

Also, while we are here, trim down the entries added to the generated
go.mod. We need the main module, and the replaced module info.
We may want to pin golang.org/x/mobile version if possible, but I don't
know a reliable way to achieve that yet.

Fixes golang/go#37048
