conn: don't enable GRO on Linux < 5.12 
Kernels below 5.12 are missing this:

    commit 98184612aca0a9ee42b8eb0262a49900ee9eef0d
    Author: Norman Maurer <norman_maurer@apple.com>
    Date:   Thu Apr 1 08:59:17 2021

        net: udp: Add support for getsockopt(..., ..., UDP_GRO, ..., ...);

        Support for UDP_GRO was added in the past but the implementation for
        getsockopt was missed which did lead to an error when we tried to
        retrieve the setting for UDP_GRO. This patch adds the missing switch
        case for UDP_GRO

        Fixes: e20cf8d3f1f7 ("udp: implement GRO for plain UDP sockets.")

That means we can't set the option and then read it back later. Given
how buggy UDP_GRO is in general on odd kernels, just disable it on older
kernels all together.

tun: use add-with-carry in checksumNoFold() 
Use parallel summation with native byte order per RFC 1071.
add-with-carry operation is used to add 4 words per operation.  Byteswap
is performed before and after checksumming for compatibility with old
`checksumNoFold()`.  With this we get a 30-80% speedup in `checksum()`
depending on packet sizes.

Add unit tests with comparison to a per-word implementation.

tun/netstack: cleanup network stack at closing time 
Colin's commit went a step further and protected tun.incomingPacket with
a lock on shutdown, but let's see if the tun.stack.Close() call actually
solves that on its own.

tun/netstack: remove usage of pkt.IsNil() 
Since 3c75945fd ("netstack: remove PacketBuffer.IsNil()") this has been
invalid. Follow the replacement pattern of that commit.

The old definition inlined to the same code anyway:

 func (pk *PacketBuffer) IsNil() bool {
 	return pk == nil
 }
