Merge bitcoin/bitcoin#29172: fuzz: set nMaxOutboundLimit in connman target

e5b9ee0221 fuzz: set `nMaxOutboundLimit` in connman target (brunoerg)

Pull request description:

  Setting `nMaxOutboundLimit` (`-maxuploadtarget`) will make fuzz to reach more coverage in connman target. This value is used in `GetMaxOutboundTimeLeftInCycle`, `OutboundTargetReached` and `GetOutboundTargetBytesLeft`.
