The vsock_diag_test program directly included ../../../include/uapi/
headers from the source tree. Tests are supposed to use the
usr/include/linux/ headers that have been prepared with make
headers_install instead.

Before check if a send returns -EPIPE, we need to make sure the
connection is closed.
To do that, we use epoll API to wait EPOLLRDHUP or EPOLLHUP events
on the socket.

Some tests can fail with transports that have a slightly
different behavior, so let's add the possibility to specify
which tests to skip.
