Vendors: pin MafiaNet v0.17.0 for in-session MTU black-hole recovery

[Segfaultd]

Bumps the MafiaNet pin from v0.16.0 (667fa4e9) to v0.17.0 (9b0e240c).

v0.16.0's 1400-byte MTU cap fixed tunnelled players on paths the handshake can probe; v0.17.0 adds the deferred follow-up for the ones it can't: a tunnel that black-holes large datagrams on the return path only (OpenVPN's defaults do exactly this — no UDP fragmentation, direction-asymmetric drops, OpenVPN/openvpn#823), or a path that shrinks mid-session. The reliability layer now detects the black-hole signature, steps the connection's MTU down the handshake's own ladder, and re-splits every queued message that no longer fits — instead of resending the same too-large datagram until the connection times out. Ordinary packet loss can never trigger a step-down.

Wire-compatible: RAKNET_PROTOCOL_VERSION stays at 7, no message ids move, and the split/reassembly wire format is unchanged (the new bookkeeping is sender-side only), so mixed 0.15/0.16/0.17 peers interoperate and a server-side bump helps players who have not updated. Release notes: https://github.com/MafiaHub/MafiaNet/releases/tag/v0.17.0

Verified locally: a reconfigure fetches the pinned commit and MafiaNetStatic, Framework, and FrameworkServer all build clean against it.

Poem

A rabbit checks the CMake line
The newer pin now fits just fine
MTU shadows learn to flee
Protocol seven stays in key
Hop, hop, the build moves cleanly crescentine
