NETLINK_KOBJECT_UEVENT sockets send udev-style messages for device events.
gVisor doesn't have any device events, so our sockets don't need to do anything
once created.
systemd's device manager needs to be able to create one of these sockets. It
also wants to install a BPF filter on the socket. Since we'll never send any
messages, the filter would never be invoked, thus we just fake it out.
Fixes #1117
Updates #1119

sockets, pipes and other non-seekable file descriptors don't
use file.offset, so we don't need to update it.
With this change, we will be able to call file operations
without locking the file.mu mutex. This is already used for
pipes in the splice system call.

Store enough information in the kernel socket table to distinguish
between different types of sockets. Previously we were only storing
the socket family, but this isn't enough to classify sockets. For
example, TCPv4 and UDPv4 sockets are both AF_INET, and ICMP sockets
are SOCK_DGRAM sockets with a particular protocol.
Instead of creating more sub-tables, flatten the socket table and
provide a filtering mechanism based on the socket entry.
Also generate and store a socket entry index ("sl" in linux) which
allows us to output entries in a stable order from procfs.

SockType isn't specific to unix domain sockets, and the current
definition basically mirrors the linux ABI's definition.

This should fix the socket Dirent memory leak.
fs.NewFile takes a new reference. It should hold the *only* reference.
DecRef that socket Dirent.
Before the globalDirentMap was introduced, a mis-refcounted Dirent
would be garbage collected when all references to it were gone. For
socket Dirents, this meant that they would be garbage collected when
the associated fs.Files disappeared.
After the globalDirentMap, Dirents *must* be reference-counted
correctly to be garbage collected, as Dirents remove themselves
from the global map when their refcount goes to -1 (see Dirent.destroy).
That removes the last pointer to that Dirent.
