Fix breadcrumbs.service: default.target not graphical-session.target

graphical-session.target ships RefuseManualStart=yes and BOS has no
session manager to activate it properly (the same issue worked around
for breadclipd) - breadcrumbs doesn't need a Wayland session anyway,
so default.target avoids the problem entirely.
