Comment:

 weasel has set CARGO_HOME to an empty writeable directory in the tor-rust
 jenkins builds.

 But he says that we should make sure cargo only writes to the build
 directory, for the sake of Debian, Ubuntu and other distributions.

 We should do whatever other Rust packages do.

 If there's no clear answer, I suggest that we make the build directory
 CARGO_HOME if:
 * CARGO_HOME is unset or not writeable, and
 * HOME is unset or not writeable
