[PATCH] client: unset WAYLAND_SOCKET env variable

[Pekka Paalanen]

WAYLAND_SOCKET contains a file descriptor that is an open connection to
a Wayland server. It is private to us, and makes no sense to relay the
same value (or any value) to our child processes.

Unset the environment variable to prevent it from being accidentally
relayed to other processes.
