Background gvfs restart to avoid blocking user.slice thaw

The post-sleep hook runs before systemd thaws user.slice, so a
synchronous systemctl --user restart hangs for ~90 seconds waiting
for the frozen user manager to respond — blocking the entire resume.

Background the restart with a short delay so it executes after
user.slice is thawed.
