Hi,

The build fails while cargo resolves metadata for crates/graph:

  error: no matching package named `maplit` found
  location searched: directory source `/usr/share/cargo/registry`

crates/graph/Cargo.toml declares maplit as a dev-dependency, and cargo
metadata still needs it available in Debian's offline registry setup.

The attached patch adds the missing Build-Depends on librust-maplit-dev.

Verified with:

  debuild -b -us -uc

The build succeeds and the test suite passes:

  Ran 186 tests
  OK
