rpm: add version constraint for qubes-desktop-linux-manager

Updated qubes-vm-update isn't compatible with older
qubes-desktop-linux-manager, as cmdline arguments are slightly changed.
Add conflict with the older version. Do not use Require:
qubes-desktop-linux-manager >= 4.2.24, as the requirement dependency is
in the other direction (qubes-desktop-linux-manager use qubes-vm-update,
not the other way around), and technically qubes-desktop-linux-manager
isn't required to use qubes-vm-update.

Fixes QubesOS/qubes-issues#9341
