Since Linux 6.16 (7d8d93fdde50), SO_PASSCRED is restricted to AF_UNIX,
AF_NETLINK, and AF_BLUETOOTH sockets; getsockopt on inet sockets fails
with EOPNOTSUPP. This surfaces natively on new kernels and through
hostinet passthrough, while netstack keeps the old semantics. Accept
either behavior.

Instead, rely on the indirection through "capability_util", which is platform
agnostic. This ensures tests can be run against Linux and Fuchsia.

AllSocketPairTest.SetAndGetBooleanSocketOptions fails on the upstream linux
kernel. The behaviour has been changed by 5b0af621c3f6 ("net: restrict
SO_REUSEPORT to inet sockets").

Fixes:
* Pass through some more recvmmsg flags.
* Pass through some more get/setsockopt flags.
* Allow IP_MULTICAST_LOOP/TTL to have variable size, since it can be 8 or 32
bits.
* Convert IPPROTO_IP to IPPROTO_TCP/UDP so it can be returned properly by
getsockopt(SO_PROTO).
* Disable one test that requires CAP_SYS_ADMIN on the host. Will have to come
back to these.

This was mostly a matter of allowing more get/setsockopts. Also had to support
getsockopt with a null option, because apparantly Linux allows that.

The timeout is currently 200ms and causes occasionally flakes in Fuchsia infra
(https://fxbug.dev/112974). Increase it to 1s.

In Linux, the minimum buffer size used in setsockopt for SO_SNDBUF and
SO_RCVBUF option is the value defined in SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF.
(These values depend on the struct sk_buff size).
The minimum buffer size for SO_RCVBUF in gVisor is 4KiB. Since the value in
Linux is based on sk_buff size, it is not useful to have the same limits set
in gVisor. Added a syscall test to verify the minimum receive buffer size.

TCP is fully supported. As with SO_RCVBUF, other transport protocols perform
no-ops per DefaultSocketOptionsHandler.OnSetReceiveBufferSize.
