git-daemon: use 'test_atexit` to stop 'git-daemon'

Use 'test_atexit' to run cleanup commands to stop 'git-daemon' at the
end of the test script or upon interrupt or failure, as it is shorter,
simpler, and more robust than registering such cleanup commands in the
trap on EXIT in the test scripts.

Note that in 't5570-git-daemon.sh' the daemon is stopped and then
re-started in the middle of the test script; take care that the
cleanup functions to stop the daemon are only registered once.
