[Buildroot] [PATCH] package/rustc: allow cargo sub packages to download using 'git'

[guillaume.bressaix at gmail.com]

From: "Guillaume W. Bres" <guillaume.bressaix at gmail.com>

Adding this simple command to the general cargo configuration
will allow sub packages (with their own cargo.toml file)
to resolve dependencies using 'git'. Without this,
we only support builtin packages or manually downloaded
packages refered to with a local full path.
