This partially fixes <https://issues.guix.gnu.org/54786>, allowing the 'jami'
and 'jami-provisioning' system tests to pass again.
In version 0.9.0, Shepherd constructors are now run concurrently, via
cooperative scheduling (Guile Fibers). The Jami service previously relied on
blocking sleeps while polling for D-Bus services to become ready after forking
a process; this wouldn't work anymore since while blocking the service process
wouldn't be given the chance to finish starting. The new reliance on Fibers
in Shepherd's fork+exec-command in the helper 'send-dbus' procedure also meant
that it wouldn't work outside of Shepherd anymore. Finally, the
'start-service' Shepherd procedure used in the test suite would cause the Jami
daemon to be spawned multiple times (a bug introduced in Shepherd 0.9.0).
To fix/simplify these problems, this change does the following:
1. Use the Guile AC/D-Bus library for D-Bus communication, which simplify
things, such as avoiding the need to fork 'dbus-send' processes.
2. The non-blocking 'sleep' version of Fiber is used for the 'with-retries'
waiting syntax.
3. A 'dbus' package variant is used to adjust the session bus configuration,
tailoring it for the use case at hand.
4. Avoid start-service in the tests, preferring 'jami-service-available?' for
now.

For single-disk installs (external USBs) and for amnesiac UEFIs, Guix is not
found using its default Grub EFI bootloader location of
/boot/efi/EFI/Guix/grubx64.efi means the Guix install will not be found.
To handle this, we can place the bootloader file in the UEFI specification
location, overwriting any other OS that may have placed a file there. This
location is namely /boot/efi/EFI/BOOT/BOOTX64.efi. Grub has explicit support
