Make each WRT/MiniBrowser use the unique wayland socket string.

The UIProcess is a Wayland compositor so it creates its own wayland socket string to
communicate with the WebProcess. However, all the UIProcesses create the same wayland
socket string. As a result, the first wrt instance can only render a web page well.

This patch allow to create a unique wayland socket string using process ID
instead of the return value of epoll_create1.
