  [WPE][GTK] Web process cache suspend/resume does not work, WebProcessProxy::processIdentifier is not the pid of the actual web process
https://bugs.webkit.org/show_bug.cgi?id=262794

Reviewed by Carlos Garcia Campos.

We'll use Unix credentials to send the actual pid of the child process
to the parent process.

This could be done using the WebKit IPC connection, but the code is
much simpler if we create a separate socket for this.
