Copy IPV6-mapped-IPV4 addresses correctly in native code (#9996)
Motivation:

8dc6ad5 introduced IPV6-mapped-IPV4 address support but
copied the addresses incorrectly. It copied the first
4 bytes of the ipv6 address to the address byte array
at offset 12, instead of the other way around.

7a547aa implemented this correctly in netty_unix_socket.c
but it seems the change should've been applied to
netty_epoll_native.c as well.

The current behaviour will always set the address to
`0.0.0.0`.

Modifications:

Copy the correct bytes from the ipv6 mapped ipv4 address.
I.e. copy 4 bytes at offset 12 from the native address
to the byte array `addr` at offset 0.

Result:

When using recvmmsg with IPV6-mapped-IPV4 addresses,
the address will be correctly copied to the byte array
`addr` in the NativeDatagramPacket instance.
