support/download/cargo-post-process: make manifest path configurable

Browse Source 
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.
