[PATCH wayland 1/2] support specifying custom directories for the client and server

[Imran Zaman]

Hi

support specifying custom directories for the client and server
sockets through environment           variables.

This is in order to support nested compositor architectures where
system compositor using drm-backend is shared among multiple child
compositors using wayland-backend.
