GoKeyify looks not work as general.

[Shane-XB-Qian]

refer: dominikh/go-tools#834

or: to reproduce: had a struct:

type Rectangle struct {
	Length int
	Width  int
}

now: cursor on letter '2'
rr := Rectangle{2, 0} cur

then run :GoKeyify, it reported:
vim-go: non-zero exit code: can't find package containing '../x.go'

What did you expect to happen?

	rr := Rectangle{
		Length: 2,
		Width:  0,
	}

What happened instead?

vim-go: non-zero exit code: can't find package containing '../x.go'

as ticket dominikh/go-tools#834 comment, looks vim-go should be not easy to make it work also, so close this now.
looking forward gopls would integrate keyify soon.
