reconfigure: Correctly re-throw SRFI-34 exceptions on Guile 3.
Previously, we'd just print an ugly backtrace when running on Guile 3 because the '%exception throw would not be caught anywhere. Reported by Arne Babenhauserheide <arne_bab@web.de> in <https://bugs.gnu.org/40496>. * guix/scripts/system/reconfigure.scm (install-bootloader-program): In 'catch' handler, match '%exception and use 'raise-exception' instead of 'throw' to rethrow in that case.
