installer: Add core dump support.
Fixes: <https://issues.guix.gnu.org/58733> * gnu/installer.scm (installer-program): Enable core dump generation. * gnu/installer/dump.scm (%core-dump): New variable. (prepare-dump): Copy the core dump file. * gnu/installer/newt/welcome.scm (run-welcome-page): Propose to report an installation that previously generated a core dump.
