installer: Skip the backtrace page on user abort.

Browse source 
When the user aborts the installation because a core dump is discovered or the
installation command failed, displaying the abort backtrace doesn't make much
sense. Hide it when the abort condition is &user-abort-error and skip directly
to the dump page.

* gnu/installer/steps.scm (&user-abort-error): New variable.
(user-abort-error?): New procedure.
* gnu/installer/newt/final.scm (run-install-failed-page): Raise a
user-abort-error.
* gnu/installer/newt/welcome.scm (run-welcome-page): Ditto.
* gnu/installer.scm (installer-program): Hide the backtrace page and directly
propose to dump the report when the a &user-abort-error is raised.
