Johnathan Corgan b836800e31 Warn when the Docker test build's cargo target is outside the checkout ...

Cargo fingerprints a workspace crate relative to the workspace root and
judges it by file modification times, so a CARGO_TARGET_DIR shared by two
checkouts can hand one checkout the other's binaries without compiling
anything. testing/scripts/build.sh honours an exported CARGO_TARGET_DIR,
and now warns when it resolves outside the checkout. A per-checkout
directory outside the tree is legitimate and cannot be told apart from a
shared one, so this warns rather than refuses.
