xdg-desktop-portal 0.9 switched from attachments as an array of URIs to
attachment_fds as an array of fds, but flatpak-xdg-utils 1.0.0 switched
from attachments as an array of URIs to attachments as an array of ints
(not fds!), resulting in failure to interoperate.
Fixes: f8ed903c "email: Pass attachments as fds"
Resolves: #50
