union: Delete duplicates when passed the same input several times.
* guix/build/union.scm (union-build): Prepend "." to the result of
`union-tree', to match the expectations of `delete-duplicate-leaves'.
Don't do mkdir when SUBDIR is ".".
* tests/union.scm ("union-build"): Keep duplicates in %BOOTSTRAP-INPUTS.
