Bug 236437 – [GTK][WPE] Refactor the XDGDBusProxy launcher to simplify it and fix some issues

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Carlos Garcia Campos]

I've noticed several issues:

 - r289369 introduced an issue with old versions of bwrap that fails to mount over an existing file, so we need to ensure we only bind the original socket for the a11y socket and not the session bus one.
 - bindA11y is GTK specific for some reason, which means WPE doesn't have a11y under the sandbox.
 - The names of the socket paths for a11y and session bus use the same pattern dbus-proxy-XXXXXX, it helps to use a different one.
 - The code to get the a11y DBus address is now duplicated in PlatformDisplay, we can just use the PlatformDisplay to get the address.

Much better function name, indeed!
