Alban Crequy d715ccc391 ebpf: handle fd_install events from tcptracer-bpf

Since https://github.com/weaveworks/tcptracer-bpf/pull/39, tcptracer-bpf
can generate "fd_install" events when a process installs a new file
descriptor in its fd table. Those events must be requested explicitely
on a per-pid basis with tracer.AddFdInstallWatcher(pid).

This is useful to know about "accept" events that would otherwise be
missed because kretprobes are not triggered for functions that were
called before the installation of the kretprobe.

This patch find all the processes that are currently blocked on an
accept() syscall during the EbpfTracker initialization.
feedInitialConnections() will use tracer.AddFdInstallWatcher() to
subscribe to fd_install  events. When a fd_install event is received,
synthesise an accept event with the connection tuple and the network
namespace (from /proc).
