bug#45187: git download defaults to origin/master

Hi Kyle,

> Subject: [PATCH v2] git: Update cached checkout to the remote HEAD by default.
>
> Fixes <https://bugs.gnu.org/45187>.
> Reported by Ricardo Wurmus <rekado@elephly.net>.
>
> update-cached-checkout hard codes "master" as the default branch, leading to a
> failure when the clone doesn't have a "master" branch.  Instead use the remote
> HEAD symref as an indicator of what the primary branch is.
>
> * guix/git.scm (resolve-reference): Support resolving symrefs.
> (update-cached-checkout, latest-repository-commit): Change the default for REF
> to the empty list and translate it to the remote HEAD symref.
> (<git-checkout>): Change branch field's default to #f.
> (git-checkout-compiler): When branch and commit fields are both #f, call
> latest-repository-commit* with the empty list as the ref.
