scripts: substitute: Replace some leave calls with raise. 

These calls happen inside of with-error-handling, so the effect should be the
same, but this opens up the possibility of using this code in a program that
doesn't want to exit when one of these error conditions is met.

* guix/scripts/substitute.scm (download-nar, process-substitution): Use raise
formatted-message rather than leave.
