Since 96ba94843b we don't spray packets to all machines on the network.
So we can allow ourself to raise the TTL limit, this allows users who run L3 IGMP Routing infrastructure to pass meshtastic frames over UDP.

The packet.readBytes API is not available on all targets:
- RP2040 & RP2340
- yet to be written portduino API
Instead pass the data buffer as-is.
It also removes a memcpy which do not need to exists.
I've tested it successfully on a tbeam.

A smart router or switch is able to snoop the multicast address to
only send the packets to nodes listening on the multicast address.
Before all machines reachable on the L2 layer would receive the packet.
From the manpage:
> arch - print machine hardware name (same as uname -m)
Arch Linux does not have the `arch` alias, only `uname`, so use `uname` to fix this issue:
> ```
> ./bin/build-native.sh: line 18: arch: command not found
