rust-mixed-index: rename variable to make the next change clearer

We're going to add another mmap reference holder, so let's rename this one
first.

{
    "conduit_uri": "https://phab.mercurial-scm.org/api",
    "phabricator.uri": "https://phab.mercurial-scm.org/",
    "repository.callsign": "HG",
    "arc.land.onto.default": "@",
    "base": "hg:.^"
}
