bootstrap: %bootstrap-inputs: Wrap input lists into thunks.

* gnu/packages/bootstrap.scm (%bootstrap-inputs): Change to procedure.  Update
users; prepares for Mes bootstrap.
* gnu/packages/commencement.scm (%boot0-inputs, %boot1-inputs, %boot2-inputs,
%boot3-inputs, %boot4-inputs, %boot5-inputs, %boot-6-inputs): Change to
procedure.  Update users.
* tests/builders.scm (%bootstrap-inputs, %bootstrap-search-paths): Make a
procedure, filter on package?.  Update users.
