[meta-lts-mixins][scarthgap/rust][PATCH 26/35] cargo_common.bbclass: add subdir argument to git dependency to let cargo find crate

From: George Refseth <[email protected]>

When git referenced crate dependency dependens on (root) workspace virtual
manifest, when patching path the path to the folder containing the crate
within the referenced repo need to be added to the patching process.
A subdir argument is added to address this need.

Example usage when repo contains an api crate defining the api for org/repo:
SRC_URI:append = "git://[email protected]/<org>/<repo>.git;name=api;destsuffix=repo-api;subdir=crates/api;type=git-dependency"
