Willy Tarreau b93758cec9 MINOR: checks: make sure spread-checks is used also at boot time 
This makes use of spread-checks also for the startup of the check tasks.
This provides a smoother load on startup for uneven configurations which
tend to enable only *some* servers. Below is the connection distribution
per second of the SSL checks of a config with 5k servers spread over 800
backends, with a check inter of 5 seconds:

- default:

    680 08:01:55
    922 08:01:56
    962 08:01:57
    899 08:01:58

    886 08:02:03
    846 08:02:04
    903 08:02:05
    894 08:02:06
    178 08:02:07

The load is much smoother from the start, this can help initial health
checks succeed when many target the same overloaded server for example.
This could be backported as it should make border-line configs more
reliable across reloads.
