David Edmundson 768e5fb7f4 [autotests] Fix race condition in ShellClient::testUnresponsiveWindow
Summary:
The test executable "kill" freezes itself after 1ms, supposedly after
showing a window.

However showing a window is not syncronous on wayland, it's illegal to
map a buffer before getting a configure event from the server.

This patch removes any potential for a race by having the server tell
our test executable when to freeze.

Test Plan: Test still passed
