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.

As discussed on #guix, this should wait until 1.1.0 is branched off to avoid
having to update translations.

This reverts commit 9f1b7871.

Various places while downloading or compiling guix prints
the source URL. This change makes the URL easier to use by
placing a space between the URL and the trailing dots.
