Use lazy evaluation for dependencies of the zipDistributable task (#1474)

The createDistributable task is generated by the Compose plugin, so it's not
always available when zipDistributable task is configured. Using lazy
evaluation by wrapping these expressions in a Provider avoids that issue.

This issue was encountered in the Nix build, presumably because it uses
single-threaded compilation.
