randr: Adjust master's last set time with slaves

Browse Source 
In prime configurations master's last set time may not be latest
and greatest, adjust it with slaves last set time, pick up greatest
one. Otherwise xserver may end with events which has
lastSetTime < lastConfigTime even if that's not
the case and confuse xrandr client.

[hdegoede: rebase on "xrandrprovider: Do not use separate lists for unbound /
 source / offload slaves"]
