selftests: fill in some missing configs for net

We are missing a lot of config options from net selftests, it seems:

tun/tap:     CONFIG_TUN, CONFIG_MACVLAN, CONFIG_MACVTAP
fib_tests:   CONFIG_NET_SCH_FQ_CODEL
l2tp:        CONFIG_L2TP, CONFIG_L2TP_V3, CONFIG_L2TP_IP, CONFIG_L2TP_ETH
sctp-vrf:    CONFIG_INET_DIAG
txtimestamp: CONFIG_NET_CLS_U32
vxlan_mdb:   CONFIG_BRIDGE_VLAN_FILTERING
gre_gso:     CONFIG_NET_IPGRE_DEMUX, CONFIG_IP_GRE, CONFIG_IPV6_GRE
srv6_end_dt*_l3vpn:   CONFIG_IPV6_SEG6_LWTUNNEL
ip_local_port_range:  CONFIG_MPTCP
fib_test:    CONFIG_NET_CLS_BASIC
rtnetlink:   CONFIG_MACSEC, CONFIG_NET_SCH_HTB, CONFIG_XFRM_INTERFACE
             CONFIG_NET_IPGRE, CONFIG_BONDING
fib_nexthops: CONFIG_MPLS, CONFIG_MPLS_ROUTING
vxlan_mdb:   CONFIG_NET_ACT_GACT
tls:         CONFIG_TLS, CONFIG_CRYPTO_CHACHA20POLY1305
psample:     CONFIG_PSAMPLE
fcnal:       CONFIG_TCP_MD5SIG

Try to add them in a semi-alphabetical order.

Fixes 62199e3f1658 ("selftests: net: Add VXLAN MDB test")

Fixes c12e0d5f267d ("self-tests: introduce self-tests for RPS default mask")

Fixes ae5439658cce ("selftests/net: Cover the IP_LOCAL_PORT_RANGE socket option")

These are not all the options we're missing. Since the merge window is over I may not have the time to dig into it myself :(

Adding Fixes tag for 3 semi-random commits which I think missed things. The full list would be very long.

Fixes ae5439658cce ("selftests/net: Cover the IP_LOCAL_PORT_RANGE socket option")

MPTCP coverage is a recent (Dec '23) addition. I must have missed it.

Fortunately we don't need to backport that far. Should be:
