In most pure Rust packages, the Cargo.toml manifest is at the root
directory, which is why we could call "cargo vendor" without
specifying the path of the manifest.
However, other packages, such as python-cryptography, which have parts
implemented in Rust, have their Cargo.toml located in a specific
subdirectory.
This commit extends the cargo-post-process download script to
understand a BR_CARGO_MANIFEST_PATH environment variable, which allows
a package to pass the location of the Cargo.toml file. If not passed,
"Cargo.toml" is used, preserving the existing behavior for other
packages.

In order to be package agnostic, the install phase is now using cargo
instead of install. TARGET_CONFIGURE_OPTS is now also set when running
cargo in order to support cross compiling C code within cargo.
This commit also adds support/download/cargo-post-process to perform
the vendoring on Cargo packages.
The <pkg>_LICENSE variable of cargo packages is expanded with ",
vendored dependencies licenses probably not listed" as currently for
all packages, the licenses of the vendored dependencies are not taken
into account.
