This enables the use nft bridge reject with bridge vlan filtering.
It depends on a kernel patch to make the kernel preserve the
vlan id in nft bridge reject generation.

On families other than 'ip', the rule
ip protocol icmp
needs a dependency on the ip protocol so we do not treat e.g. an ipv6
header as ip.
Bridge currently uses eth_hdr.type for this, but that will cause the
rule above to not match in case the ip packet is within a VLAN tagged
frame -- ether.type will appear as ETH_P_8021Q.
Due to vlan tag stripping, skb->protocol will be ETH_P_IP -- so prefer
to use this instead.

Commit 3e6ab2b335142 added restraints on reject types for bridge and
inet families but aparently those were too strict: If a rule in e.g.
inet family contained a match which introduced a protocol dependency,
icmpx type rejects were disallowed for no obvious reason.
Allow icmpx type rejects in inet family regardless of protocol
dependency since we either have IPv4 or IPv6 traffic in there and for
both icmpx is fine.
Merge restraints in bridge family with those for TCP reset since it
already does what is needed, namely checking that ether proto is either
IPv4 or IPv6.
Fixes: 3e6ab2b335142 ("evaluate: reject: check in bridge and inet the network context in reject")

... to avoid resetting e.g. the ssh session to the vm that runs
nft-test.py.

Rearrange the directory to obtain a better organization of files and
tests-suites.
We end with a tree like this:
tests
|
.--- py
.--- shell
.--- files
This was suggested by Pablo.
