Kernel: Allow fchmod() and fchown() on pre-bind() local sockets

In order to ensure a specific owner and mode when the local socket
filesystem endpoint is instantiated, we need to be able to call
fchmod() and fchown() on a socket fd between socket() and bind().

This is because until we call bind(), there is no filesystem inode
for the socket yet.
