pkg/plugins: use a dummy hostname for local connections
For local communications (npipe://, unix://), the hostname is not used,
but we need valid and meaningful hostname.

The current code used the socket path as hostname, which gets rejected by
go1.20.6 and go1.19.11 because of a security fix for [CVE-2023-29406 ][1],
which was implemented in  https://go.dev/issue/60374.

Prior versions go Go would clean the host header, and strip slashes in the
process, but go1.20.6 and go1.19.11 no longer do, and reject the host
header.

Before this patch, tests would fail on go1.20.6:

pkg/ is a collection of utility packages used by the Moby project without being specific to its internals.

Utility packages are kept separate from the moby core codebase to keep it as small and concise as possible. If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the Moby organization, to facilitate re-use by other projects. However that is not the priority.

The directory pkg is named after the same directory in the camlistore project. Since Brad is a core Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!

Because utility packages are small and neatly separated from the rest of the codebase, they are a good place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
