rustpkg: Build dependencies into the correct workspace when using --rust-path-hack

When invoked with the --rust-path-hack flag, rustpkg was correctly building
the package into the default workspace (and not into the build/ subdirectory of the
parent directory of the source directory), but not correctly putting the output
for any dependencies into the default workspace as well.

Spotted by Jack.
