File name breaking go modules

[James Jesudason]

When running go modules command from another project there is a file that's breaking the integration:

```
go get github.com/snapcore/snapd/asserts latest
go get latest: unrecognized import path "latest" (import path does not begin with hostname)
go: finding github.com/snapcore/snapd/asserts latest
go: finding github.com/snapcore/snapd latest
go: extracting github.com/snapcore/snapd v0.0.0-20190327122014-ef87afe95139
-> unzip /Users/jjesudason/go/pkg/mod/cache/download/github.com/snapcore/snapd/@v/v0.0.0-20190327122014-ef87afe95139.zip: malformed file path "cmd/snap-confine/spread-tests/distros/debian.": trailing dot in path element
go get github.com/snapcore/snapd/asserts: unzip /Users/jjesudason/go/pkg/mod/cache/download/github.com/snapcore/snapd/@v/v0.0.0-20190327122014-ef87afe95139.zip: malformed file path "cmd/snap-confine/spread-tests/distros/debian.": trailing dot in path element
```

This file `cmd/snap-confine/spread-tests/distros/debian.` has a trailing full stop.

Why are you using snapd as a library?

[James Jesudason (jamesj)]

It gets used for multiple projects that need assertions. The Serial Vault is one, and I'm also working on an agent that uses snapd API. The agent uses assertions as a part of the device identification with a cloud service.

Any update on this? I have the same problem updating https://github.com/CanonicalLtd/serial-vault to the `go mod` and pin version of snapd

This should be fixed in recent snapd master, the PR that fixed this was: https://github.com/snapcore/snapd/pull/7634

Looks like it's fixed in https://github.com/snapcore/snapd/commit/4e8d74d5f6a37c31b48f0a34d5793d95e92db6c4 and awaiting release - thanks Zygmunt!

Apologies, I missed your update there Ian - thanks
