refactor(users/multi/whitby): use the depot's own source location attribute. r/1897

The depot knows where it is, not because it knows where it isn't, but
because it does an "import ./." at the top level and then makes this
path value available in the attrset passed to the rest of the tree.

My home-manager config on whitby previously involved manual
specification of the depot checkout location on whitby, however this
isn't necessary when the depot can already magically tell us where it
is.
