tests: Depend on daemon for integration test

The carefree developer might try running meson test
before meson compile, leaving them with a failing integration test:

Start of lfb-integration tests
dbus-daemon[326641]: [session uid=1000 pid=326641 pidfd=8] Activating service name='org.sigxcpu.Feedback' requested by ':1.0' (uid=1000 pid=326640 comm="$(pwd)/_build/tests/te")
+ exec $(pwd)/_build/src/feedbackd
$(pwd)/_build/run: 18: exec: $(pwd)/_build/src/feedbackd: not found
